Trip Amplifier and Process Limit Alarms

A trip amplifier is defined as a device that allows an Analog signal to be converted to a Relay output. The Relay output controls the variation of a physical unit in a system measured by temperature sensors or normalized signals and operates when the measured value goes outside pre-determined limits, energizing or de-energizing the relay controlling devices like valves and actuators.
What Does Datexel offer?
Datexel manufactures a large range of Trip Amplifiers and Process Limit Alarms that accept universal inputs and provide relays outputs. The DAT5024P is an economical choice of process limit alarm with the ability of being PC programmable for RTD's Thermocouples, Resistance, voltage or current inputs, and has 2 relays outputs (SPDT) with delay timers.
The DAT5024AO is a process limit alarm with the ability to provide an analog output which is proportional to the analog input.
The DAT5028 features a universal input trip amplifier and is also an isolated signal converter and has a local display with up to 4 relays and is DIP switch programmable. The inputs can be Thermocouples, RTD, mV, mA, Resistance, Potentiometers or Voltage. They can be supplied fully configured or set up by PC or DIP switches.
