Overview 4-20mA ("four to twenty”), is an analog electrical transmission standard used by Otis Instruments for some of its ambient gas sensors and monitors. The signal is a current loop where 4mA represents zero percent signal, and 20mA represents 100 percent signal (full scale of the sensor assembly).
Measuring Current If the value measured is 0mA, then: the loop wires are broken, the sensor assembly is not powered up, the sensor assembly is malfunctioning, or the monitor is malfunctioning. A DMM (digital multi meter) or Current Meter may be used to test a 4-20mA signal. Place the DMM or Current Meter in line with the loop and measure current.
Specifications Operating Voltage: 24 Volts DC (nominal; 22-26 Volts DC), 120/240 Volts AC Compatibility: Otis WireFree and wired (4-20mA input) sensor units Channels: Gases: all that are supported by the sensor assemblies Wired Output: RS-485 Modbus Relays: four Dry-Contact (5 Amp) w/ 4 Amp Fuses...
