| GAS DETECTION CONTROLLERS
CETCI’s family of gas detection controllers are designed to accept inputs from a number of remote transmitters (analog and/or digital) and perform control functions such as automatically activating exhaust fans, make-up air fans, alarm devices, etc. PAC and PDC controllers utilize microprocessor circuits allowing these controllers to be completely field configurable by the end user. A 2-line, backlit LCD provides the user with scrolling information about the connected transmitters and the built-in audible / visual alarms provide alarm notification to the user. The PAC accommodates 4 analog inputs and provides 4 analog outputs (4-20 mA). The PDC accommodates 8 analog inputs and 120 digital transmitters or 128 digital transmitters on a communication network. Both controllers provide a wide range of functionality.
