Intrinsically safe inputs:

• Proximity sensor, NAMUR standard, closing non-potential contact, transistor switch NPN, PNP OC.
• Auxiliary voltage supply 8.2 V_DC.

Non-intrinsically safe outputs:

• Relay or opto-relay contacts.
• Common minus "-" terminal for each pair of outputs.

Power supply:

• 24V_DC.

Additional information:

• Alarm indication of shorted- or opened-circuit in the input line (LED).
