Limit Alarm Unit DG 35200

Monitoring of analog standard signals

The configurable Limit Alarm Switch DG 35200 is used for limit monitoring and processing of unipolar and bipolar standard signals. A SPST relay or optionally an isolated, passive transistor switch (Open-Collector) is available at the output.

  • Universal input for current and voltage
    and integrated transmitter supply
  • Easy configurable via DIP switches or via USB
    limit point, hysteresis and mode of operation can be directly set, limit point adjust also in operation via teach-in function
  • Switchable timer and special functions
    Switch-on delay, switch-off delay and wiper function, Memory and window functions
  • 3-Port-Separation
    protection against switching errors due to parasitic voltages or ground loops
  • Extremely slim design
    6.2 mm slim housing for a simple and space saving DIN rail mounting
  • Optional In-Rail-Bus mounting rail connector
    allows for fast and economical installation
  • Protective Separation acc. to EN 61140
    Protects service personnel and downstream devices against impermissibly high voltage
  • 5 Years Warranty
    Defects occurring within 5 years from delivery date shall be remedied free of charge at our plant (carriage and insurance paid by sender)

The configurable Limit Alarm Switch DG 35200 is used for limit monitoring and processing of unipolar and bipolar standard signals. A SPST relay or optionally an isolated, passive transistor switch (Open-Collector) is available at the output.

The Limit Alarm Unit monitors standardized current and voltage signals, and transmits the signal to the switching output. A transmitter power supply is provided for the operation of 2-wire and 3-wire transmitters.

The configuration is carried out via DIP switch or USB interface. The switch point can be taught-in and corrected during operation with the front-side Teach-In buttons. The alarm Unit has an adjustable switch-on delay, switch-off delay and a wiper function. Further settings such as memory function and window function can be programmed via USB interface.

The input is protected against polarity reversal and short circuit. The power supply can be provided via the connection terminal blocks or via the optional In-Rail-Bus. The switch status and the device status are indicated by LEDs on front panel. If the device is operated via the In-Rail-Bus, a common fault message is available on the status line.
