Description

Description

The PHA-52 dual alarm modules provide an ideal way to add alarm capability to a control system loop. The module’s two relays each have setpoint and deadband controls and an LED to indicate on/off relay status. Relay phasing switches individually select each relay to operate in response to increasing or decreasing input signal value. For compatibility with many systems, input levels are user selectable. The PHA-52 accepts 0 to 50 mV, 0 to 100 mV, 0 to 5 Vdc.
