Description

XCL-VEA-CO2VV-RM reports over a Modbus RTU digital output, and its application areas include refrigerated systems (leak detection), laboratories, high tech manufacturing and confined spaces.

Mechanically the unit is a 500 g module of 113 x 113 x 59 mm in polycarbonate, charcoal in colour, and rated IP65, Type 4 (NEMA 250). Humidity of 0 to 99% (non-condensing) is tolerated and storage runs 0 °C to +30 °C. Conductors of 0.5 to 1.5 mm², or 20 to 16 AWG, terminate in pluggable rising clamp style connections, integral alarm status LEDs report at the head and Bluetooth 4.0 (Bluetooth Low Energy) is available for a compatible smart device within 10m (mobile device dependent).

Conformity is to EN/UL/IEC61010-1, certification to CSA-C22.2 No. 61010-1-12, EMC to EN 50270, radio to RED, FCC and BT SIG, plus AS 1668.2. The sensor is replaceable via XCL-SC-CO2VV, with XCL-FILTER, XCL-M20-CG and XCL-COVER as further items.

XCL-VEA-CO2VV-RM is a factory calibrated carbon dioxide gas detector working on a percentage scale, covering 5.0% v/v and adjustable from 1.0% v/v. Installation places it in-line on a VESDA-E VEA microbore tube network, coupled with flexible tubes, and the tube itself is micro bore at 6 mm (1/4”) OD.

Reporting is over Modbus. The digital output is Modbus RTU, carried on an RS 485 Modbus line, while two relays provide switching rated at 240 V AC or 24 V DC, 5 A. VSC and VSM4 integration extends that further, reaching the operating status of Modbus version detectors remotely, and the same signals suit PLCs, HVAC, BMS or FACP.

Supply on the Modbus branch is 9 to 32V DC around a 24 VDC nominal figure; peak inrush draws 850 mA at 24V DC, consumption reaches 1.2W for a carbon dioxide head on Modbus and the relay version accounts for a further 0.6W total. Operating temperature spans −20 °C to +50 °C, and it works within 95 to 110 kPa of atmospheric pressure.
