5. OUTPUT RELAYS
The unit IM3G-VX includes four (R1, R2, R3, R4) user programmable plus one diagnostic (R5) output
relays.
The number of output relays can be increased by the addition of one or two optional Relay Expansion
modules REX-8.
The modules REX-8 are for protruding mounting and are controlled by the master module IM3G-VX via
a screened twisted pairs of cables connecting dedicated RS485 serial ports (see diagram herebelow).
The module REX-8 includes eight (RA, RB, RC, RD, RE, RF, RG, RH) user programmable plus one (R-
Diag) diagnostic output relays
The master module IM3G-VX can control all together up to sixteen output relays

from the first optional REX-8 module RA
– RB – RC – RD – RE – RF – RG – RH
- 4
from a second optional REX-8 module RI(RA+RB)
– RJ(RC+RD) – RK(RE+RF) – RL(RG+RH)
This second unit REX-8 is configured (by internal Dip-Switch) to operate the eight relays two by two in
parallel (only four user programmable outputs with double number of available contacts)
Any of the function featured by the IM3G-VX can be programmed to control up to four out of the sixteen
user programmable output relays
