Limit Alarms (Analog Input, Relay Output)

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/release points programmed via DIP switches or via a programming module, depending on the model; relay outputs interface to other process equipment.
