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

The PSC-154 controller monitors and controls TDS/EC levels for high-output commercial systems. It has an extended range, digital calibration, on-screen temperature, tri-color display, and 4-20mA output.

Features:

1. Large, bright L.E.D. display

2. The 4-20mA output signal can connect to a PLC to record values

3. An alarm will sound if the TDS /EC level rises above the user-set level

4. A switch will control a device based on the set point

5. On-screen temperature display (°C/°F)

6. Includes one sensor probe (part #SP-1-PSC)

Specifications:

1. EC Range: 0~9999µS

2. TDS Range: 0~5000 ppm

3. Temperature Range: 1~75°C; 33~167°F

4. Accuracy: ±2% (of the reading)

5. Conversion Factor: NaCl (avg. 0.5)

6. Resolution: 0.1µS/ppm (0~999); 1µS/ppm (1000~9999)

7. ATC: Yes (1~65°C)

8. Calibration: Digital by push button

9. Set-Point: Single point, controlled by on-screen up/down buttons (to any point within the range)

10. Relay Control: The unit will open or close a circuit via dry contacts when the ppm/µS level reaches or exceeds the control setting (simple switch). It can be used to control a pump, solenoid valve or other device.

11. Relay Voltage: 5V

12. Output Signal: 4-20mA

13. Output Accuracy (mA): ±1%
