TDS 200 Controller

Economical controller designed with the features and reliability of a much more expensive instrument Reliable power supply withstands voltage fluctuation from 85 to 265 VAC Adjustable hysteresis prevents rapid relay switching near set points Adjustable TDS factor temperature coefficient and selectable cell constants Galvanically isolated 4 20 mA output for remote monitoring or hard copy recording Removable terminal strips offer quick and easy connections Battery back up of memory maintains set up if power fails These sturdy compact controllers withstand voltage fluctuations from 85 to 250V AC DC They are ideal for installation were electrical fluctuations are common or install them in series throughout areas of differing electrical conditions Advanced setup mode lets you select cell constant TDS factor temperature coefficient manual or automatic temperature compensation hysteresis band and more It also lets you view previous calibration points The 1 8 DIN housing is ready to install in standard panels and NEMA rated boxes Includes mounting hardware accepts probes with stripped ends and Pt 100 RTD ATC elements Measures TDS C TDSRange 0 to 10 00 ppm 0 to 100 0 ppm 0 to 1000 ppm 0 to 5 00 ppt 0 to 10 00 ppt 0 to 100 0 ppt TDSResolution 0 01 ppm 0 1 ppm 1 ppm 0 01 ppt 0 1 ppt Special features Conductivity to TDS factor adjustable from 0 40 to 1 00 Calibration one point slope calibration Control accuracy 1 full scale TemperatureRange 10 0 to 110 0 C TemperatureResolution 0 1 C TemperatureAccuracy 0 5 C TemperatureCalibration offset up to 10 C Control type on off Number of inputs one Number of set points two OutputControl 2 SPDT nonpowered relays 6A at 110 VAC 250 VAC max OutputCurrent 4 20 mA output isolated Hysteresis 0 to 10 of range adjustable for each set point Electrical isolation yes galvanically Temperature Sensor Pt 100 Temperature Compensation automatic or manual from 0 to 100 C Password protection two levels Display 4 digit 14 segment scrolling LED Operating Temperature 0 to 50 C Housing 1 8 DIN Dimensions 3 3 4 W x 1 7 8 H x 6 D Shipping weight 0 5 lb 0 2 kg
