Series Description

Senva TG UL Series wall and duct sensors can be ordered as individual sensors or as any dual combination of CO / NO2 / CO2 / Methane / Propane / Hydrogen / Oxygen / H2S / Ammonia / Refrigerants sensor in a shared enclosure.   The analog output model features two outputs that support daisy chain wiring - multiple sensors may be used in a parallel sequence (0-10V) for cost-effective coverage of large areas. The unit can also act as a stand-alone controller, utilizing the relay for exhaust fan operation, or the output for direct control of a VFD. The BACnet/Modbus model supports BACnet MS/TP & Modbus network communication in one unit. Standard features include network auto-configuration, a programmable fan relay, LED indicators, integrated display, and audible alarm.
