The sensor signal will be compared with the set limit values. In case of overshooting or undershooting, the output relays react according to the set configuration.

Two relay outputs (synchronous switching) can be configured as MIN or MAX alarm in open-circuit or closedcircuit operation with the analog control electronics.

All setting elements are located behind the openable front cover and can also be operated when the unit is mounted. The switching points and the switching hysteresis can be
adjusted with potentiometers. The monitoring states are indicated by yellow LEDs.

The relay changeover contacts switch high power loads up to 6 A. Input, power supply and the outputs are safely galvanically isolated from each other.

The Protective Separation and the 24 V DC power supply make the DG 3602 and DG 3632 universally applicable for all measurement and industrial applications, as well as for building automation.
