    • 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 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 for analog output in 0…20mA (or 4…20mA) configuration.

 

The analogue output of the GS300 is an active analogue output, which is why it must not be powered. The resistance of
analogue input shall be:

  • If the output signal is in voltage: Rmin=1K
  • If the output signal is in current: Rmax=300ohm

RS485 SERIAL PORT

  • 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
