PROGRAMMER FOR REVERSE OSMOSIS SYSTEMS – PRG11
Programmer for reverse osmosis (RO) plants, power supply 230 V~, output for 24 V~ solenoid valve. Conductivity measurement of inlet water: K=5, range 2000 µS/cm. Conductivity measurement of outlet water: K=5, range 200 µS/cm.
The PRG11 controller is an electronic unit specifically designed for the control of reverse osmosis systems, perfect for different installation configurations; in fact, you can mount it on the osmosis system’s frame or on the wall.
It is equipped with an internal clock to schedule the filter washings, and with two inputs for conductivity probes, for measurement of the water both entering and exiting the osmosis unit.
The programmer comes carefully calibrated and configured at the factory, accordingly with the plant needs and therefore ready to the installation, without requiring any customer’s intervention.
TECHNICAL FEATURES
- Two inputs for conductivity probes, to monitor the water both entering and exiting the osmosis unit
- Thermo-compensation of readings
- Real time clock, with buffer battery, to schedule the filter cleaning at set times
- RS232 serial port for communication with PC, data recorder, RW14
- Outputs for filter pump control, adjustment and alarm
- Multi-language menu (Italian, English, French, Spanish)
- Power supply 230 V~ 50 Hz (115 V~ on request)
- IP65 housing designed for wall installation or mounting on the frame of the osmosis system
