OS3050 Reverse Osmosis ControllerThe unit type OS3050 or type OS3051 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.


  • Menu driven programming utilising “two line” LCD-display
  • Choice of languages (English, French, German, Italian, Spanish or Dutch)
  • Adaptable to user specific requirements by built-in programmable options.
  • Simple control utilising easy to follow symbols.
  • Universally applicable for various sizes of installation
  • Desalinated water production controllable by hand or level switches
  • Control of the maintenance situation by means of a code choice possible
  • Programming a service telephone number possible
  • Substantial status information employing INFO key: actual input and output conditions, service telephone number, software version, programming situation of the annunciation and malfunction relays, rinse interval, rinse times, instrument probe cell constants
  • Large green LED-display showing permeate- and raw water conductivity plus the relative
  • Permeate-conductivity as a percentage value of the raw water conductivity or raw water temperature
  • Optional card for 2 recorder outputs 0(4)-20mA (conductivity / temperature)
  • Input: production-stop, storage tank full/empty, excess pressure, low pressure, concentrate-monitoring or alarm reset, motor protection switch, temperature feeler (optional)
  • Integrated conductivity meter with automatic range switching
  • Conductivity range according to the instrument probe cell constants from 0,1 to 1 00 000 µS/cm
  • The instrument probe cell constants programmable from 0,01 to 10,00 cm-1
  • Manual or automatic temperature compensation
  • Duplicate conductivity meter and temperature reading as an available option
  • Thermo switch with annunciation contact for 115/230 Volt pressure pump as available option Output: pressure pump (protection), input valve, rinse valve for concentrate and permeate, annunciation and malfunction contact
  • Security of program information against supply failure, as all program information is stored without accu
  • Large capacity microprocessor with “Watchdog”, illegal “Operation code” and frequency monitoring
  • Manufactured in accordance with EMC codes of practice; by means of galvanic isolation between the micro-processor and the in- and output circuits, plus extra built-in filter
  • Available for wall-mounting and panel-mounting
  • Available (input /output) : 24/24V, 115/115V, 230/230V
