ÈNTINUUM
I/O Systems
This manual describes the installation, care and use of all Continuum I/O modules.
The
Continuum
Ethernet-based intelligent building system allows you to mix and match
various combinations of DIN rail-mounted moduleshigh density I/O, CPU and power
supply, and your choice of several user interface modulesin a
single
controller location
to meet your building’s control and monitoring needs. With the
Continuum
system, as
your network grows, simply add or replace I/O modules as needed.
The
Continuum
I/O modules feature a sleek, lightweight casing designed for natural
convection cooling, and a 3-position front cover for easy, hands-free access. Built-in
quick-release fasteners at the back of each I/O module are provided for DIN rail
mountingno tools required. These fasteners also snap into a locked position for panel
mounting. Input and output connectors are located at the bottom of each I/O module and
are removable for easy field access and maintenance. All
Continuum
modules are
designed for mounting in an optional NEMA 1-style
Continuum
enclosure.
The
Continuum
I/O modules communicate with the
Continuum
NetController CPU
module. Like all
Continuum
modules, the I/O modules snap together directly via built-in
connectors on either side so network expansion is quick and easy. Both power
transmission and communication signals between the
Continuum
power supply module,
NetController CPU module, and all I/O modules feed through this connection. For added
convenience in certain applications, such as door control or lighting control, a single
module or groups of I/O modules can be remotely located and connected using approved
cable and powered from a local 24 VDC power supply. Each I/O module features its own
push-button for quick and easy network commissioning.
This document covers the standard Input and Output modules. For information
regarding the special Continuum enclosure door-mounted display modules

I/O System Introduction
The Continuum I/O system is comprised of a series of modules separated by function
that connect via a common electrical communications bus. Each functional component is
enclosed in a plastic case containing all of its connections to the outside world. Modules
are connected to a central controller via a standard five conductor connector.
The Continuum system includes at least one power supply and a single controller
module. I/O modules provide the controller with the ability to interface with the outside
world. They connect directly and communicate with the CPU. The following is a typical
architecture drawing of a Continuum System:
Continuum I/O modules are available in INPUT, OUTPUT, MIXED and DISPLAY
varieties.

Mechanical Installation
Each I/O module, except the Display variety, is enclosed in the same standard plastic
case that is designed to be mounted on a standard DIN rail or fastened to a panel.
Note: In order to meet agency requirements, it is necessary that the modules along
with the power supply and controller be housed in another metal enclosure i.e., a
NEMA box or the new Andover Controls Continuum enclosure.
The standard I/O module plastic case is illustrated below:
Status indicators and operator switches are located on the indicator panel. Other
switches available for module configuration may be accessed by lifting the hinged door to
the module as shown.

Wiring to controlled points or sensors is accomplished via a standard removable screw
terminal block located at the bottom of the module behind the door. An open area at the
bottom of the case allows wires to exit in an appropriate manner.
On the back of each module are molded DIN rail guide fingers. The design allows the
module to easily hook onto and slide along a standard DIN rail.
With the mounting brackets extended outward, hook the module onto the DIN rail as
shown below:

Enclosure-Mounted Modules
The modules that are designed to be mounted to the new Andover Controls Continuum
enclosure fit into openings left by removing panels in the front door.
The new enclosure provides a place to mount a power supply, CPU and up to ten DIN rail
mounted I/O modules. Several display modules can be affixed to the front panel.
The enclosure is a 6” deep NEMA box with integral display panels, DIN rails, cable
troughs and a battery storage compartment.
The enclosure features three DIN rails and cable management accessories. Use of the
new enclosure is not required, however, it provides a convenient method of constructing
small local systems.

Power-CPU Connections
The Continuum NetController CPU module includes a connector on the upper right
side of its case for further distribution of the 24 VDC input power and special I/O
communications signals to all I/O modules. Continuum I/O modules use these signals
for power and communications as well.
The power-I/O connector is a five pin male assembly that is designed to easily insert
directly into the left side (input) connector of any I/O module. The signals within that
connector are as follows:
PIN Function
5 +24 VDC
4 24 VDC Return
3 Ground
2 Comm B
1 Comm A
The system power supply generates a +24 VDC source for all modules in the system.
This power source is received through the input power connector on the left side of
the CPU module and sent through to pins 4 and 5 of this connector. Pin 3 (Ground) is
intended as a signal ground connection.
Communications between the CPU and I/O modules is through a two-signal serial
interface that can be internally configured as either RS 485 or Echelon LON FTT-10.
Pins 1 and 2 (Comm B and Comm A) provide the electrical connection for this
interface.

Connection of I/O Modules
The CPU can directly connect to I/O without the use of cables through a system of
built-in plugs and jacks. All I/O modules include two complementary module inter-
connectors.
Creating a system is as simple as physically plugging the modules together.
In vertical extended systems, I/O modules may be located above or below other
modules. In this case, cable assemblies bridge the I/O modules together.
The cable necessary to connect the CPU and external I/O modules is five conductor
and would be attached using a plug-in screw terminal connector. Connection
between the modules is one-to-one straightforward wiring as shown below:
This connector is available from Andover Controls under part number 01-2050-283;
Wieland manufactures it under part number 25.340.0553.0.

Maximum Number of I/O Modules
There is no operational limit to the number of I/O modules connected to the CPU except
the capacity of the power supply. It is possible to insert auxiliary power supplies into the
I/O bus to increase the number of modules supported.
To determine the maximum number of I/O modules your system can support, subtract the
power requirements for each module from the maximum available from your power
supply.
PS 120/240 AC 50 U, UPS power supply provides 35 Watts of power
PS 120/240 AC 50, non-UPS power supply provides 50 Watts of power
PS –48 DC 50, Battery operated power supply provides 50 Watts of power
NetController requires 15 Watts of power
Start by subtracting the NetController from the power available from your power supply.
PS 120/240 AC 50 U
35 – 15 = 20 Watts of available power for I/O
PS 120/240 AC 50
50 – 15 = 35 Watts of available power for I/O
PS –48 DC 50
50 – 15 = 35 Watts of available power for I/O
The power requirements for each I/O module is listed in the
Continuum I/O System
Reference Guide
ACC # 30-3001-499 and can be found on individual data sheets.
Maximum Length of I/O Bus
A repeater is necessary if the cable lengths get too long. The following are
recommendations regarding cable lengths for both RS-485 and FTT-10 interfaces:
RS-485 Repeater required if length is >2000 ft. (610 m) or after 32 modules.
FTT-10 Repeater required if length is >8858 ft. (2700 m) bus topology
>1640 ft. (500 m) free topology
Connecting Remote I/O Modules with RS-485
The Continuum system allows I/O modules to be placed in a remote location from the
CPU (NetController). However, long cable lengths can cause signal communications
problems on the Power/I-O bus.
When locating an I/O module remotely it is necessary to add a 120 terminator to the
bus to compensate for the distance. The terminator must be connected at both ends of
the bus for proper operation.

Continuum I/O System Reference

Termination Guidelines
The following are typical installations that indicate the placement of the terminator:
Simple CPU and 1 remote I/O Module:
The I/O Bus that needs to be terminated is the one formed by the cable attaching the
remote module to the CPU. In this case, a terminator resistor is connected across the
communications lines (pins 1 & 2) directly at the NetController and again at the remote
I/O module.

CPU with local and 1 remote I/O Module:
The I/O Bus that needs to be terminated is the one formed by the cable that starts at
the NetController and ends at the remote module. The bus that extends from the
NetController through the local I/O stack does not need termination. In this case, the
terminator resistor is connected directly across the communications lines (pins 1 & 2) at
the NetController and again at the remote I/O module.
