Modular smart relays and analogue I/O extension modules
To improve performance and flexibility, Zelio Logic modular smart relays can be fitted
with analogue I/O extension modules with 10-bit resolution.
The inputs accept 0-10 V, 0-20 mA and Pt 100 type signals.
Using a Zelio Logic modular smart relay with a
c
24 V supply in conjunction with an
analogue 4 I/O extension module makes it possible to obtain up to 30 I/O, including
8 analogue inputs and 2 analogue outputs.
The analogue I/O extension module must be connected to an SR3
ppp
BD modular
smart relay with a
c
24 V supply.
Description
The analogue I/O extension module has the
following on its front panel:
1
Two retractable fixing lugs
2
Terminals for connection of the inputs.
3
Terminals for connection of the outputs
4
A connector for connection to the smart
relay (powered via the smart relay).
5
Locating pegs.

Combination of modular smart relays with
communication and I/O extension modules
d
The order shown above must be observed when using a
network communicationmodule and an analogue I/O
extension module.
An I/O extension module cannot be fitted before the
network communication module.
