Principais características

AC/DC trip amplifier
2 adjustable alarm limits
Galvanically isolated 3.75 kVAC
Front-programmable
3-digit LED display
24 VDC or universal supply

VISÃO GERAL

The front-operated push buttons are used for programming the different standard functions.
A password can prevent access for changing parameters.

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.
