Working Principle
The X-DI3202A receives digital input signals from field devices through a termination board or field wiring assembly. Each channel is monitored for valid signal levels, open circuits, short circuits, and internal faults. The module processes the input states and provides monitored digital information to the HIMA safety controller. Continuous diagnostics ensure that faults in the module, wiring, or field devices are detected and reported.
Installation Requirements
Install in a HIMA-approved rack or backplane
Use the correct termination board for X-DI3202A
