The card is connected to a gas sensor with a 4-20 mA current output and makes available the contacts of 3 relays: Fault contact (NC), Pre-alarm contact (NO) and Alarm contact (NO).

In addition, the card has two terminals (OUT), thanks to which it can be directly connected to a VEGA series input module, intercommunicating the gas sensor with the loop of an analog control unit with INIM addressing.

Two trimmers allow to regulate the intervention threshold of the pre-alarm and the alarm.
