I/O Module

A various group of different I/O modules can

be connected to the LON network for further

data acquisition of e.g. a SCADA system,

main station, PC or other LON nodes.

Direct coupled LON sensors:

Output types:

Ø Relay

Ø Triac

Ø Analogue 0-10V

Input types:

Ø Analogue 0-10V

Ø Analogue 0 (4) -20mA

Ø Temperature inputs (Pt 100/Pt1000)

Ø Digital input

Examples:

A digital input module could contain opto-

coupler isolated digital inputs, each having

separate signal grounds. This makes it a

device, which is ideal for acquisition of

digital DC and AC process signals. It is

used for processing binary and digital val-

ues, e.g. switch signals or binary sensor

signals. Other applications are acquisition

and measurement of frequency, time, pulse

width and count.

Optionally relays with switch over contacts

can be included in some modules. These

relays can be used for signalling error con-

ditions or for output of logic equations.

Normally input and relay output states are

signalled by LEDs.

Combined digital output / input modules

contain groups of galvanic separated high-

side switches.

Furthermore, the outputs can be configured

as digital DC inputs for mixed applications.

Different external load supply voltages can

be used. Outputs can be connected in par-

allel for increasing load current. This makes

it a device, which is ideal for output of digital

process signals or for plc-interfacing. Other

applications include output of pulses with

specific frequencies, widths, or pulse se-

quences. Devices such as electronic valves,

contacts or lamps can be switched immedi-

ately.

Transistor outputs are normally protected

against short-circuit, overload, wrong load

voltage polarisation, high internal dissipation

and chip temperature.

Relay modules are used for message based

switching of external currents or signalling of

states.

Example for the usage of this module (soft-

ware not included as a standard): Signalling

of reaching upper or lower limits of values.

Hysteresis and time delays are programma-

ble in both transition directions (on --> off /

off --> on).

Other possible operating modes include

clock generation, delay generation, or sim-

ple switch amplifier.

Triggering or switching activities usually oc-

cur as a consequence of message receipt

(switch command, updating of input val-

ues).

All relay states are normally signalled with

LED's.

Self calibrating, integrating analogue input

modules contains analogue inputs normally

both for current, or alternatively for voltage.

It is used for processing slowly changing

analogue values, e.g. sensor or transmitter

signals.

Analogue output modules normally have

galvanic isolated analogue outputs with

common signal ground. Mostly they can

operate as voltage output (0...10V) or as

current output (0/4..20mA or alt. 0...5V).

This makes it a device, which is ideal for

output of analogue process signals in con-

trol applications or for PLC-interfacing.

Service-LED and service-pins are normally

accessible from the front side.
