EWS OS3051/1 RO Controller Wall Mount 24/24V

Product Description

Description

The OS3050/3051 RO controller is universal applicable for automatic monitoring and control of reverse osmosis plants. The controller is equipped with a conductivity meter optional is a second conductivity meter and temperature meter. Also optional is a circuit board with two recorder outputs (0(4) – 20 mA). There are five possible stages : "Stand by", "Production", "Rinse after production", "Rinse during standby" and "Maintenance". Adaptable to user specific requirements by built-in programmable options. The programmed configuration will be stored into non volatile memory and therefore not be affected by power loss.

Features
