1.1 Features and Applications

The Model 1057 analyzer offers three sensor inputs and four current outputs thus reducing the cost

per loop and saving panel space. The pH signal input board supports pH, ORP, and Ion-Selective

Electrode measurements. The conductivity signal input board supports contacting conductivity,

resistivity, total dissolved solids, salinity and percent concentration curves for special applications.

The modular design allows signal input boards to be field replaced making configuration changes

easy. Conveniently, live process values are always displayed during programming and calibration

routines. Standard features include isolated inputs, eight embedded local languages, four 4-20mA

current outputs, four alarm relays and removable connectors for power and current outputs.

Quick Start Programming: Exclusive quick start screens appear the first time the Model 1057 is

powered. The instrument auto-recognizes each measurement board and prompts the user to

configure each sensor loop in a few quick steps for immediate deployment.

Menus: Menu screens for calibrating and programming are simple and intuitive. Plain language

prompts and help screens guide the user through these procedures.

4-Electrode Conductivity: For applications requiring wide range conductivity measurements, use

Rosemount Model 410VP 4-electrode sensor. It is not affected by fouling and is

supported by the same contacting conductivity signal board as traditional 2-electrode sensors.

Three Sensor Inputs: The Model 1057 accepts one, two or three isolated inputs. Inputs are isolated

from other signal sources and earth ground.

Four Current Outputs: Four 0/4-20 mA current outputs are electrically isolated. Outputs are fully

scalable and can be programmed to linear or logrithmic modes. Output dampening can be enabled

with time constants from 0 to 999 seconds.

Enclosure: The instrument fits standard ½ DIN panel cutouts. The versatile enclosure design supports

panel-mount, pipe-mount, and surface/wall-mount installations.

Smart pH Sensors: Avoid buffer calibrations in the field. Use Rosemount SMART pH sensors to

automatically calibrate the measurement loop when connected to Model 1057. Choose from a

complete range of SMART pH sensors suited to most applications.

• M

ulti-parameter instrument – up to three inputs. Choose pH/ORP/ISE or contacting

conductivity/resistivity in any combination.

• L

arge display – large easy-to-read process measurements.

• Easy to install – modular boards, removable connectors, easy to wire power, sensors, an

outputs.

• Intuitive menu screens with advanced diagnostics and help screens.

• SMART - Enabled - compatible with SMART pH sensors.

1.3 Contacting Conductivity (Codes -20, -30 and -40)

Measures conductivity in the range 0 to 600,000 µS/cm (600mS/cm). Measurement choices are

conductivity, resistivity, total dissolved solids, salinity, and % concentration. The % concentration

selection includes the choice of five common solutions (0-12% NaOH, 0-15% HCl, 0-20% NaCl, and 0-25%

or 96-99.7% H

2

SO

4

). The conductivity concentration algorithms for these solutions are fully

temperature compensated. Three temperature compensation options are available: manual slope

(X%/°C), high purity water (dilute sodium chloride), and cation conductivity (dilute hydrochloric acid).

Temperature compensation can be disabled, allowing the analyzer to display raw conductivity. For

more information concerning the use and operation of the contacting conductivity sensors, refer to

the product data sheets.

Note: When contacting conductivity sensors are used for sensor 1 and sensor 2, Model 1057 can

derive an inferred pH value called pHCalc. pHCalc is calculated pH, not directly measured pH.

Note: Selected 4-electrode, high-range contacting conductivity sensors are compatible with

Model 1056.

Input filter: time constant 1 - 999 seconds, default 2 seconds

Response time: 3 seconds to 100% of final reading

Salinity: Uses Practical Salinity Scale

Total Dissolved Solids: Calculated by

1.4 pH/ORP/ISE (Codes -22, -32, and -42)

For use with any standard pH or ORP sensor. Measurement choices are pH, ORP, Redox, ammonia,

fluoride or custom ISE. The automatic buffer recognition feature uses stored buffer values and their

temperature curves for the most common buffer standards available worldwide. The analyzer will

recognize the value of the buffer being measured and perform a self stabilization check on the sensor

before completing the calibration. Manual or automatic temperature compensation is menu

selectable. Change in pH due to process temperature can be compensated using a programmable

temperature coefficient. For more information concerning the use and operation of the pH or ORP

sensors, refer to the product data sheets.

Model 1057 can also derive an inferred pH value called pHCalc (calculated pH). pHCalc can be derived

and displayed when two contacting conductivity sensors are used as sensor 1 and sensor 2.

3.1 General

The Model 1057 is easy to wire. It includes removable connectors and slide-out signal input boards.

3.1.1 Removable Connectors and Signal Input Boards

Model 1057 uses removable signal input boards and communication boards for ease of

wiring and installation. Each of the signal input boards can be partially or completely removed

from the enclosure for wiring. The Model 1057 has three slots for placement of up to three

signal input boards and one communication board.

Note: If the UL option code has been ordered, a plastic insulator shield surrounds the entire power

supply board (AC power supply only). The protective insulator shield does not appear in this photo.

3.1.2 Signal Input Boards

Slots 1, 2 and 3 are for signal input measurement boards. Wire the sensor leads to the

measurement board following the lead locations marked on the board. After wiring the sensor leads

to the signal board, carefully slide the wired board fully into the enclosure slot and take up the excess

sensor cable through the cable gland. Tighten the cable gland nut to secure the cable and ensure a

sealed enclosure.

Note: that signal input board 3 is inserted into slot 1. Board 3 is inverted in the slot to allow board

components to face to the right. Board 3 uses a long ribbon cable to connect to the main PCB. Boards

1 and 2 use a split ribbon cable to connect both signal boards to a common connector on the

main board.

3.1.3 Alarm Relays

Four alarm relays are supplied with the switching power supply (84 to 265 Vac, 03 order code) and

the 24 Vdc power supply (20-30 Vdc, 02 order code). All relays can be used for process measure

ments or temperature. Any relay can be configured as a fault alarm instead of a process alarm.

Each relay can be configured independently and each can be programmed as an interval timer,

typically used to activate pumps or control valves. As process alarms, alarm logic (high or low acti

vation or USP*) and deadband are user-programmable. Customer-defined failsafe operation is

supported as a programmable menu function to allow all relays to be energized or not-energized

as a default condition upon powering the analyzer. The USP alarm can be programmed to activate

when the conductivity is within a user-selectable percentage of the limit. USP alarming is available

only when a contacting conductivity measurement board is installed.

3.2 Preparing Conduit Openings

There are six conduit openings in all configurations of Model 1057. (Note that four plugs are provid-

ed upon shipment.)

Note: Use watertight fittings and hubs that comply with your requirements. Connect the conduit

h

ub to the conduit before attaching the fitting to the analyzer.

3.3 Preparing Sensor Cable

The Model 1057 is intended for use with all Rosemount pH/ORP and contacting

conductivity sensors. Refer to the sensor installation instructions for details on preparing

sensor cables.

3.4 Power, Output and Sensor Connections

All field wiring must be rated for 75 °C or higher. Each instrument includes a printed label inside the

enclosure stating this wiring requirement.

3.4.1 Power Wiring

Two Power Supplies are offered for Model 1057:

a. 24 Vdc (20 – 30V) Power Supply (-02 ordering code)

b. 84 – 265 Vac Switching Power Supply (-03 ordering code)

AC mains (115 or 230V) leads and 24 Vdc leads are wired to the Power Supply board which is mounted

vertically on the left side of the main enclosure cavity. Each lead location is clearly marked on the

Power Supply board. Wire the power leads to the Power Supply board using the lead markings on

the board.

3.4.4 Sensor Wiring to Signal Boards

Wire the correct sensor leads to the measurement board using the lead locations marked directly on

the board. After wiring the sensor leads to the signal board, carefully slide the wired board fully

into the enclosure slot and take up the excess sensor cable through the cable gland.

For best EMI/RFI protection use shielded output signal cable enclosed in an earth-grounded metal

conduit. Connect the shield to earth ground. AC wiring should be 14 gauge or greater. Provide a

switch or breaker to disconnect the analyzer from the main power supply. Install the switch or

breaker near the analyzer and label it as the disconnecting device for the analyzer. Keep sensor and

output signal wiring separate from power wiring. Do not run sensor and power wiring

in the same conduit or close together in a cable tray.

3.4.2 Current Output Wiring

All instruments are shipped with four 4-20 mA current outputs. Wiring locations for the outputs are

on the main board which is mounted on the hinged door of the instrument. Wire the output leads to

the correct position on the Main board connectors using the lead markings (+/positive, -/negative) on the

b

oard. Male mating connectors are provided with each unit. Use a 3/32” wide standard blade

screwdriver.

Note:

Twisted pairs are required to minimize noise pickup in the 4-20 mA current outputs. For high EMI/RFI

environments, shielded sensor wire is required and recommended in all other installations.

3.4.3 Alarm Relay Wiring

Four alarm relays are supplied with the switching power supply (84 to 265 Vac, -03 order code) and

the 24 Vdc power supply (20-30 Vdc, -02 order code). Wire the relay leads on each of the independ-

ent relays to the correct position on the power supply board using the printed lead markings

(NO/Normally Open, NC/Normally Closed, or Com/Common) on the board.
