OC5000 controller

The OC5000 controller is designed for automatic or manual control of reverse osmosis unit and provides:

• automatic switching on and off of the equipment upon signal;
• emergency shutdown of the equipment by signals from dry-running sensors, overpressure in the module;
• shutdown of equipment on the external STOP signal.
