DCC Dual Channel Controller
Available from Critical Environment Technologies Canada Inc.
The DCC Dual Channel Controller is a comprehensive and dependable, self-contained gas detection system that offers one or two channel configurations for monitoring toxic, combustible and solid state refrigerant gases.
Sensor configurations include, two internal electrochemical sensors (one must be CO), or one internal electrochemical and one remote catalytic or remote solid state sensor or a remote 4-20 mA transmitter.
Field configurable settings are done through an easy to navigate, comprehensive menu structure. Other features include two 4 - 20 mA outputs that can be used for VFD control, one configurable 4 - 20 mA input, two alarm level line voltage, two SPDT dry contact relays with field configurable time delays and trigger levels, a field selectable integral audible alarm and an LCD digital display with LED indicators for channel alarm status and fault conditions.
It comes standard with a water / dust tight, corrosion resistant ABS / polycarbonate enclosure with a hinged, secured door. With the optional splash guard installed, the enclosure is IP54 rated and ideal for use in water spray or wash down applications.
Automated calibration and other maintenance procedures are simple and easily performed in the field. For parking garage applications, our proprietary Calibration Extending Firmware (CEF) takes into account the aging of the toxic gas sensors so that less frequent calibrations are required.
