PR electronics 2231 Trip amplifier - special device. The front-operated push buttons are used for programming the different standard functions. A password can prevent access for changing parameters. Galvanically isolated 3.75 kVAC. 24 VDC or universal supply. Alarm detector in connection with measurement of AC/DC current or voltage signals. The unit is used where accurate setpoint setting and different alarm functions are required. The unit can be used as a single or dual trip amplifier. Used in applications where programmable parameters such as hysteresis, setpoint, reset, active relay for increasing or decreasing signal, delay and input signal need to be set.
