Switch Amplifier DG 31000

Input for NAMUR, SN, S0, DC sensor, Contact, V AC/DC, PNP, NPN and Push-Pull, configurable per DIP switches

The configurable switch amplifier DG 31000 is used to capture, amplify and supply of industrial binary signals. A SPST relay or optionally an isolated, passive transistor switch (Open-Collector) is available at the output.

  • Universal Binary Input
    for all common industrial status signals
  • Easily configurable via DIP switches
    Sensor type, action direction and mode of operation directly selectable
  • Switchable timer functions
    Switch-on delay, switch-off delay and wiper function
  • 3-Port Isolation
    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 fast and cost-effective installation and provides a common fault message
  • 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 switch amplifier DG 31000 is used to capture, amplify and supply of industrial binary signals. A SPST relay or optionally an isolated, passive transistor switch (Open-Collector) is available at the output.

The switching amplifier detects the status of 2- and 3-wire sensors, binary signals and AC/DC voltages und transmit the state to the switching output. The input is protected against polarity reversal and short circuit. The connected sensors can be supplied by the switching amplifier or externally.

The mode of operation and action direction can be switched with DIP switches. The device has an adjustable switch-on delay, a switch-off delay and a wiper function.

The auxiliary power can be supplied via the connection terminals or via the optional In-Rail-Bus connector. The switching status and the device status are indicated by LEDs on the front panel. If the device is operated via the In-Rail-Bus, a common fault message is available on the status line.
