Typical Wiring Schemes
Non-Redundant Module Application:
The load or actuator is connected to either
Module 1 or 2 via the AOH MTA.
Redundant Modules Application:
The load or actuator is connected to both
Module 1 and Module 2 via the AOH MTA.
Figure 21–2 Typical wiring scheme for connecting load field terminals. Only the basic AOH
MTA circuitry is illustrated.
