SC-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 extended range, digital calibration, on-screen temperature, tri-color display, and 4-20mA output.
- 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 on the set point.
- On-screen temperature display (C/F)
- Includes one sensor probe (part #SP-1-PSC)
- EC Range: 0-9999 µS
- TDS Range: 0 – 5000 ppm
- Temperature Range: 1-75°C; 33-167 °F
- Accuracy: ±2% (of the reading)
- Conversion Factor: NaCl (avg. 0.5)
- Resolution: 0.1 µS/ppm (0-999); 1 µS/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/µS level reaches or exceeds the control setting (simple switch). It can be used to control a pump, solenoid valve, or other device.
