Limit alarms accept analog inputs and provide low-limit, high-limit, or other discrete output indications based on the input value. Voltage or current input signals are compared to trip points configured via DIP switches or a programming module; relay outputs interface to other process equipment.

Limit Alarms
Category Selection
Limit alarms safeguard systems from abnormal conditions by alerting the proper personnel or taking the appropriate action when issues arise. These modules accept analog inputs and provide low-limit, high-limit, or other discrete output indications based on the input value. Their relay outputs are triggered based on comparisons between the voltage or current inputs and the trip/release points programmed via DIP switches or the programming module, depending on the model.
