RS Pro single level trip amplifiers operate from a single process input, with a single trip action. This output can be arranged so that the alarm condition is triggered either above or below the defined set point. The relay can also be configured for a Fail-Safe (energised in the stable state to de-energise in the alarm state) or Non-Fail Safe (de-energised in the stable state to energise in the alarm state) operation.

1 x SPCO relay (max. 60W load) output
Adjustable set points
High and/or low trips (user-configurable)
Bi-colour LED trip status indication: Green LED indicates stable state; red LED indicates alarm state
