URx20xI – Gas detectors with 4÷20 mA output and 4 relay outputs – IP65

Gas detector in IP65 metal enclosure with operating status LED, to warn of gas alarms through 4÷20 mA analogue output or at threshold limit setpoints (pre-alarm, level 1 and 2 alarms, failure) that can be freely selected using 4 relay outputs (with optional card UZR20.4 ).

Power supply: 11÷28 Vdc
Signal outputs: 4÷20 mA
Command outputs: 4 SPDT relays (with card UZR20.4)
Sensor: S (Standard) or P (Professional)
Protection rating: IP65
Ambient temp.: -20 °C/+50 °C

Please contact head office for any gas not included in the list below
