2231 Trip Amplifier

Quick Overview

The 2231 Trip Amplifier is a microprocessor-based unit allowing very accurate setting of process parameters. Each unit is supplied with basic calibration data, allowing the inputs to be programmed to the required signal range without re-adjustment. The user interface of the trip amplifier consists of three push buttons and a 3-digit LED display. The push-buttons can be used for selection of function and for setting any parameter, including set point, reset, active relay for increasing or decreasing signal, delay, and input signal. 2 adjustable Relay Outputs with galvanically isolated 3.75 kVAC. During operation the display shows the input signal as a %. All parameters are protected against unauthorised changes with a password. Options for 24vDC or universal 24-230vAC/DC power supply.
