Communication Interface Options

  • Optional Digital Inputs and Outputs:
  • Intrinsically safe 4-input, 4-output digital card with the following specifications:
    Inputs
    - Ui: 18 V
    - Ri: 214 Ω
    - R input: 859 Ω
    Electronic relay outputs
    - Ui: 18 V
    - Pi: 1,75 W
    In: 70 mA
  • Intrinsically safe power supply terminal, for piloting devices in ATEX zone or push-button panel. Output voltage 6V, max current 300mA.NOTE: by using the available power supply terminal, it is possible to manage the push button panel code EXPHBN in a direct way, even in a safe area, without protection barriers.

Optional Analog Output:

  • Intrinsically safe analog output, programmable at 0...10Vdc, 0...20mA or 4...20mA.NOTE: It is possible to transmit the signal directly to the safe area using the intrinsically safe protective barrier, code PFANOUTEX for analog output in 0...20mA (or 4...20mA) configuration.

RS485 Serial Output

  • 2 Optional intrinsically safe RS485 serial ports for communication with repeaters and other devices.NOTE: it is possible to transmit data directly to the safe area using the protective barrier code PFB485EX
