Note
Form-C relays are single-pole double-throw (SPDT) relays that have three positions: normally closed (NC); an intermediate position,
also called the make-before-break position (ARM); and normally open (NO).
Optional discrete digital inputs (DI)
When plugged into one of the optional card slots in the card cage, the Emerson ROC800 DI card provides eight additional discrete
digital inputs. The discrete digital inputs can monitor the status of relays, open-collector or open-drain type solid-state switches,
and other two-state devices. For more information, see ROC800-Series Discrete Input Module at Emerson's ROC 800-Series website at
