Temperature Alarm Unit DEG 3600

Control and Monitor Pt-Temperature Signals

The Alarm Unit DEG 3600 is used to monitor limit values and regulate simple automation processes in temperature measuring applications with Pt-Sensors.

  • Easy selection of operating mode
    MIN/MAX alarm switch selectable, switch point and hysteresis adjustable on front panel
  • Relay with high power handling
    SPDT relay with 6 A current switch capability
  • True 4-port separation
    Protection against erroneous measurements due to parasitic voltages or ground loops
  • Switch state indicated by LED
    Easy to adjust the set point and hysteresis
  • Protective Separation acc. to EN 50178
    Protects service personnel and downstream devices against impermissibly high voltage
  • High reliability and long-term stability
    No maintenance costs
  • Unlimited use with 24 V AC/DC power supply
    Universally applicable for all measurement and industrial applications
  • 5 Years Warrant
    Defects occurring within 5 years from delivery date shall be remedied free of charge at our plant (carriage and insurance paid by sender)

The Alarm Unit DEG 3600 is used to monitor limit values and regulate simple automation processes in temperature measuring applications with Pt-Sensors.

High reliability and Protective Separation are essential characteristics that contribute to fault-free equipment operation.

Two switch channels can be separately configured. The switch point and the switch hysteresis can each be adjusted by means of their own 12-turn potentiometer located on the unit’s front panel. The switch state is indicated by a yellow LED.

The direction of effect and the mode of operation can be switched by means of DIP switch settings. Both switch outputs can be set up as either MIN or MAX alarms. The relay contacts switch high power loads either as N.O. or N.C. contacts.

Protective Separation and the 24 V AC/DC power supply make the DEG 3600 universally applicable for all measurement and industrial applications, as well as for building automation.
