Ampcontrol's 12 Channel System Controller is a compact unit designed to accept any sensor or transmitter that gives a 4-20mA output with relay outputs on board for alarm events and programmed response.
The 12 Channel Controller accepts inputs from any two or three wire sensor/transmitter combination that gives a 4-20mA output. Typical sensor/transmitter combinations include Ampcontrol detectors for combustible gas, oxygen, toxic gas, flame as well as temperature and humidty transmitters.
The controller has twelve 4-20mA inputs, two 4-20mA outputs and four relay outputs for common Warn, Alarm, High Alarm and Fault conditions. Three push buttons, four LEDs and a sounder provide status and control functions.
A two-line alpha-numeric display provides continuous status readouts of each monitored channel, with a choice of two user-configurable formats. A specific display mode shows all input readings and status simultaneously.
