Overview

The output subsystem is the part of a GMR system that provides output data. It may consist of:

HGMR Output groups of 4 discrete blocks

HIndividual non-GMR discrete and analog blocks

The following illustration represents basic elements of an output subsystem.

4-Block Output

In a 4-block output group, each field output is supported by two Genius source outputs connected in parallel on one side of the actuator and two Genius sink outputs connected in parallel on the other. Each block in the group receives outputs from each of the three separate processors. Three Genius busses are used.

Individual Genius blocks can also be connected to the system. These blocks may be configured for either hot standby or duplex CPU redundancy if desired.

Types of Blocks in the Output Subsystem

The following discrete block versions can be configured for GMR operation. They will perform output voting and autotesting when used in GMR mode:

24/48VDC16-Circuit Source block:	IC660BBD020M
24/48VDC16-Circuit Sink block:	IC660BBD021M
12/24VDC32-Circuit Source block.	IC660BBD024N
