in the field, the redundant modules are connected so that each

sensor connects to one of the redundant modules. These

configurations are illustrated in Figure

, showing triple

redundant input modules. Each AC digital input module is

hot replaceable. In triple redundant input configurations, if a

fault occurs on one module, it can be removed and replaced

while the system continues to sense the inputs from the

remaining two input modules.
