Honeywell SPXCDULNRFD Sensepoint XCD RFD Transmitter has been specifically designed for use with remotely mounted flammable gas sensors. The XCD RFD is certified for use in Class I Div 1 rated areas and offers the one-man, non-intrusive, operation, and reduces routine maintenance time and costs. The XCD transmitter includes two programmable alarm/fault relays as well as an industry-standard 4-20mA output, with optional Modbus RTU. Calibration and relay operation of the transmitter may be adjusted via the transmitters’ backlit LCD. Outputs are automatically inhibited during adjustment thereby reducing the risk of false alarms at the control panel during maintenance.
