If for non ATEX or SIL-3 relevant purposes (e.g. indicator tablet) only 1 set of output relays or driv-
ers (usually only of CAN A) are needed, then a MSO module can be attached to the not occupied
outputs (usually CAN B) directly to the MIB without use of a MUT module. The MSO module has
LED displays for the relay condition.
NOTE: In case of failure of the bus system A the external outputs are frozen to the last value.
Connection MRO 16 TS Module
If the system is redundant, the outputs of 2 MGO modules must always be evaluated
(channel A + B). The connection of up to 5 MRO 16 TS modules (40 outputs) is achieved via
1 MRC TS module. Using 20-way ribbon cables, each of the plugs, 1–5, are connected via the
8 driver outputs (channel A + B) of the MGO modules to up to 5 MRO 16 TS modules.
The 40 driver outputs of the MGO module of channel A are connected to the MRC TS modules at
Plug A using a 40-way ribbon cable via the appropriate MUT module at the rear of the rack.
The 40 driver outputs of the MGO module of channel B are connected to the MRC TS modules at
Plug B using a 40-way ribbon cable via the appropriate MUT module at the rear of the rack
