RTD Temperature Monitor DG 3602 / DG 3632Limit Monitoring withPt, Ni, KTY and NTC Sensors The Temperature Monitors DG 3602 and DG 3632 are used for temperature control with RTD sensors in 2-wire connection. 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 closed-circuit operation with the analog control electronics. All setting elements are located behind the openable front cover and...
