40B48 Indicator/Alarm unit for force, pressure and position inputs



  • 48×48 (1/16 DIN) formats manufactured with SMT.
  • The instruments have a Lexan membrane faceplate (guaranteed to IP65) which has 3 keys, a 4-digit display, and 3 indicating LEDs for the output statuses.
  • The input signal can be selected from a wide range of sensors:
    • Potentiometer (minimum 100Ω)
    • Load cell with sensitivity auto-ranging between 1,5 and 3,3mV/V
    • Strain-gauge pressure sensor
  • The selection is made using the faceplate keys.
  • A digital input (24Vdc/4mA) is available for resetting, holding, flashing, peak handling, or releasing the latch.
  • The instruments have a maximum of 3 outputs that can be mechanical relays (5A/250V) or logic outputs (0 to 11Vdc).
  • One output of 4 to 20mA (max. 150) is available for retransmitting the measured input signal.
  • The retransmission output, the digital input, and the third output are alternatives.
  • The programming of the instrument is made easy by grouping the parameters in function blocks (CFG for the alarm hysteresis, Inp for the inputs, Out for the outputs…) and by a simplified data entry menu.
  • The configuration can be simplified even further using the PC programming kit made up of a connection cable and a menu guide program that runs under Windows (see data sheet cod. GF_eXpress).
  • A configurable personal software protection code (password protection) can be used to restrict the levels of editing and displaying the configuration parameters.


  • Strain-gauge or potentiometer input -configurable by faceplate
  • Sensor supply check
  • Easy to calibrate with sensitivity auto-ranging
  • Protected by a personal code
  • Configurable by serial link
  • Internal linearisation for engineering units
  • Labels provided for the more common physical units
  • Sampling time and trip intervention programmable between 15 and 120msec with resolution between 2000 and 8000 steps
  • Retransmission of the measured variable signal
  • 3 trip points, completely configurable from the faceplate
