Monitoring of 2nd stage area gas shut-off valves for medical gases

4 digital inputs for position valve sensors, type NAMUR or ON/ OFF
Valve status by light indicators (4 green LEDs = valve open and/ or 4 red LEDs = valve close)
Valve fault indication (green LEDs/ red LEDs alternating) only for NAMUR version Test button
Inputs programming operation by dip switches
Configuration function as base unit or repeater unit
RS485 local SDAMNet Plus network or Modbus protocol (optional)
Network address programming by dip-switch
Auxiliary outputs for collective valves open
Auxiliary outputs for collective valves closed
4 independent outputs reproducing the input status (N.C. logic)
Gas labels available: O2, N2O, Med. Air 8 bar, Med. Air 4 bar, Evac. Air, Compr. Air, Air 800, CO2, Vacuum, N2, He
