C4000 Photometric Converter

Multi Channel Photometric Converter

The C4000 converter is a multi channel controller capable of operating all optek photometric sensors. The C4000 converter allows for easy programming and operation, and can supply up to four real time configurable 4-20 mA output values correlated to any units of measure. The C4000 offers configurable relay alarms, can record and download process data, and can operate up to four sensors simultaneously.
