Product overviewThe 500 W2 Dual Channel Controller accepts industrial standard 4-20 mA analog signals from one or two gas transmitters to provide centralized monitoring of gas concentration at one or two locations. A hi-viz LED display gives clear readings even from a distance or in low light. Two user-settable alarm set points per channel and three relay contacts per alarm condition offer multiple connection options. An RS-485 port provides easy data transfer to a PC (GUI optional).
