Termination Board

HiCTB16-FBM-RAC-SC-DI16

Function

The function of the termination board and the connector pin assignment are exactly fitted to the requirements of the Foxboro FBM system.

The signal is output to the process control system via the system connector.

Information about a missing supply voltage of the isolated barriers is available for the system as a volt-free contact.

Wiring errors from field side will be reported via the same relay contact, if this function is supported by the isolators.

The termination board has a robust glass fiber reinforced plastic housing.

The termination board is mounted in the switch cabinet on a 35 mm DIN mounting rail according to EN 60175.
