Range of Process Limit Alarms.
A trip amplifier is a device that monitors analog signals and activates a relay output when the measured value exceeds defined limits. It is commonly used to control physical processes—such as temperature or current—by triggering actuators, alarms, or shutdown sequences.

Trip Amplifier and Process Limit Alarm FAQs

A trip amplifier monitors analog input signals and triggers a relay output when the signal crosses a predefined threshold. It’s used for over/under limit alarms and control actions in automation systems.

Datexel trip amplifiers accept universal inputs such as RTDs, thermocouples, resistance, voltage, and current signals.

Yes, most models can be configured using DIP switches or PC software, allowing flexible setup for your application needs.

The DAT5024AO provides both relay outputs and an analog retransmission output proportional to the input signal.
