Uniphos 500 W2 Dual Channel Controller
The 500 W2 Dual Channel Controller is designed to accept analog 4-20 mA signal from one or two transmitters providing centralized monitoring of gas concentrations at one or two locations. The hi-viz LED display aids in providing a clear reading of the gas concentration even from a distance or in low light situations. The two-user settable alarm set points per channel and 3 relay contacts corresponding to each alarm condition provide a plethora of connection options. The additional RS-485 port enables easy data transfer from the controller to a PC.
