The analog output model features 2 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, programmable fan and alarm relays, LED indicators, integrated display and audible alarm.

(1) One side of transformer secondary is connected to signal common. Dedicated transformer is recommended. No mains circuit connection allowed. In addition, it is required to use an isolated power supply that is certified by a na- tional or international standard (i.e. UL). Use of a Class 2 LPS power supply or greater is required. (2) Carbon Monoxide full scale is 1000ppm. (3) Nitrogen Dioxide full scale is 30ppm Duct Applications See Senva’s Duct Mount Gas sensing application note to learn about the use of duct-mounted sensors to provice redundancy and peace of mind.Next >
