The monitor is designed for either ceiling or wall mount and has an RS422 capability that extends an intrinsically safe interface from the sensor to the controller to several hundred feet. H2scan's hydrogen-specific sensor technology has no cross sensitivity to other combustible gases, thus eliminating false positive alarms and ensuring safety system reliability. Performance Hydrogen Sensitivity Range: 0.4% to 5% hydrogen by volume 10% to 125% hydrogen lower flammable limit Accuracy: ± (0.03 x indication + 0.2) percent hydrogen by volume Typical Response Time: T90 of 60 sec maximum Ingress Protection: IP64 capable Calibration Interval: 90 days Product Life Expectancy: 10 years Interface Options Power Barrier Input Voltage: 24 VDC nominal Power Barrier Input Voltage Range: 20 VDC to 28 VDC Intrinsically Safe Sensor Input Voltage: 10 VDC Sensor Input Voltage Range: 5 VDC to 28 VDC Input Power: 10 W Analog Output: 4 mA to 20 mA Serial Communication: RS422 Operating Conditions Operating Humidity: 0% to 95% RH Operating Temperature Range: -20ºC to 40ºC Storage Temperature Range: -40ºC to 50ºC Calibration Background Gas: Air Included Accessories Intrinsically Safe Power Barrier Armored Power / Analog Cable: 4 m Calibration Cup Optional Accessories Single Channel Intrinsically Safe Analog Output Barrier (with or without relays) Single Channel Intrinsically Safe RS422 Serial Interface Barrier Serial Interface Cable: 4 m (custom lengths available) Armored Power / Analog Cable (custom lengths available) Dimensions Total Length: 8.1 in.
