Description
Sensepoint XCD RFD Transmitter with LM25, 3/4 in. NPT entry, aluminum
The Honeywell Sensepoint XCD RFD is a remote flammable detection system for LEL monitoring applications. The XCD RFD combines the XCD transmitter with the 705 combustible Sensor, and is certified for use in Class IDiv.1 rated areas. The XCD RFD offers 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 alarm at the control panel during maintenance.
XCD RFD is supplied with all necessary accessories for easy installation. It can be mounted on a wall or 2" round support pole using the universal bracket provided. The detector is ideal for use with either conduit or steel wire armored cable and glands and includes both 3/4" NPT and M20 entries to the junction box.
