Working Principle:
The base assembly mounts in the local controller cabinet and connects to the Ovation I/O bus through the backplane. It receives power from the Ovation bus and distributes it to all installed modules. Field wiring terminates on external field termination assemblies (FTAs) or cable sets, which connect to the personality modules seated in the base. The personality modules condition field signals and pass them through the backplane to the electronics modules, which perform A/D conversion and communicate digitized data to the Ovation controller.
