GMR Input Groups

The configuration can include as many as 128 16-circuit voted discrete and 256 four-input analog input groups. (The actual I/O capacity of the system depends on the CPU type. See page 1-9).

In an system that has normally-energized discrete inputs, the following combinations of sensors and Genius inputs can be used with Genius Modular Redundancy.

Hone sensor to three Genius inputs, three busses, three PLCs

Hone sensor to two Genius inputs, two busses, two PLCs

Triple PLCs

Triple Genius Busses

Shaded items omitted

Optional Zener diode for line monitoring

Single blocks can be configured as non-voted GMR blocks, allowing them to take advantage of the GMR autotest feature. Both discrete and analog blocks can be used; however, analog blocks cannot be autotested.
