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
When plugged into one of the optional card slots on the card cage, the 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 Process Management’s ROC 800-Series web site.
