Single-channel gas controllers R8471 are designed to be mounted in 19" rack. It is designed for continuous monitoring of a 4 to 20 mA signal that is generated by an electrochemical sensor or a catalytic sensor/transmitter combination.
Controller models are available to accommodate a variety of combustible gas, oxygen and toxic gas sensors.
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.
Approvals: FM, CSA, CE and performance tests acc. to EN 60079-29-1.
The product is obsolete (withdrawn from production). It will be no longer repaired. Please contact company IP&S for the selection of a replacement controller.
