SensAlert Four Channel Gas Detection Controller

SKU: SensAlert

The SensAlert 4-Channel Controller powers and monitors up to 4 channels of gas detection. With three alarm relays per channel plus a common fault relay, the Controller provides local or remote alarm annunciation via the optional strobe and standard 90 dB buzzer. The controller has a latched alarm reset button and discrete LED value displays plus LCD displays for gas name or type and value. Discrete 4-20 mA and RS-485 Modbus RTU outputs are standard. Most SensAlert and SensAlert Plus transmitters, when used with this controller, will automatically configure the controller to display the gas type, range and factory default alarms, making system set up quick and easy.
