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:
