5. OUTPUT RELAYS
The unit MM30-D includes four (R1, R2, R3, R4) user programmable plus one diagnostic (R5) output
relays.
In the version MM30-DX 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 MM30-DX via
a screened twisted pair of cables connecting dedicated RS485 serial ports (see diagram herebelow).
The module REX-8 includes eight (RA, RB, RC, RD, RE, RF, RH, RG) user programmable plus one
(R-Diag) diagnostic output relays
The master module MM30-DX can control altogether up to sixteen output relays
- 4 internal R1 – R2 – R3 – R4
- 8 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 functions featured by the MM30-D can be programmed to control up to four out of the sixteen
user programmable output relays.
