Gas Controller R8471


Single-channel gas controllers R8471 are designed to be mounted in 19" rack.
Microprocessor based controller continuously monitors the analog 4-20mA output from any Det-Tronics gas detector: transmitter Infiniti (all gas detectors), transmitter 505 for CGS gas detector, junction box in case of C706X or PIR9400 detectors and from Eclipse gas detector directly.
R8471 continuously compares the analog signal with programmed alarm thresholds.
Controller provides visual indication from: high-visibility bar-graph of gas concentration level currently measured by the detector, high intensity alarm and status LED's, three-digit display for gas concentration or fault code readings. It is easily field programmable by use of two pushbuttons on the front panel.

Controller allows the calibration without the hazardous area de-classification. It also indicates the end of sensor's life.

Standard 4-20mA output. Optional outputs: three alarm and one fault relay.
