TDS/ EC Controller with 4-20mA Output PSC-154

FEATURES • Monitors and controls TDS/ EC levels for high output commercial systems. • Large, bright L.E.D. display. • 4-20mA output signal can connect to a PLC to record values. • An alarm will sound if the TDS / EC level rises above the user-set level. • A switch will control a device based upon the set point. • On-screen temperature display ( C/ F) . • Installs easily in minutes. • Includes one sensor probe ( at no extra cost) . • Protective cover also available ( sold separately) SPECIFICATIONS EC Range: 0-9999 µ S; TDS Range: 0 - 5000ppm Temperature Range: 1-75° C; 33-167 ° F Accuracy: ± 2% ( of the reading) Conversion Factor: NaCl ( avg. 0.5) Resolution: 0.1µ S/ ppm ( 0-999) ; 1µ S/ ppm ( 1000-9999) ATC: Yes ( 1 - 65° C) Calibration: Digital by push button Set-Point: Single point, controlled by on-screen up/ down buttons ( to any point within the range) Relay Control: The unit will open or close a circuit via dry contacts when the ppm/ µ S level reaches or exceeds the control setting ( simple switch) . It can be used to control a pump, solenoid valve or other device. Relay Voltage: 5V Output Signal: Digital 4-20mA Output Accuracy ( mA) : ± 1% Alarm: Optional steady beep ( set by user) Display: Bright 5/ 8" L.E.D. display Probe: 1/ 2" bushing, 3 meter ( 9.8 ft) shielded cable Power supply: AC 110V / AC 220V Dimensions: 7.2 x 7.2 x 10.2 cm ( 2.8 x 2.8 x 4 in.)
