Two Stage Touch Color Screen RO System Controller with sensors RO-8200
RO-8200 touch color screen double stage reverse osmosis control system is a multi-function control system with combination of four-wire resistive type touch screen with reverse osmosis process control and online conductivity monitor, it is mainly used for the system control and water quality monitor and control of reverse osmosis system.
The instrument adopts 7-inch (standard version) or 10-inch touch screen (optional version) and 800*480 resolution to realize human-computer information interaction with rich and dynamic display effects.
PLC control and conductivity transmitter acquisition circuit;
Adopt the latest high-speed MCU computer processing system in the United States, real-time control of external IO input and relay output, project design focuses on the system's high stability, high reliability, anti-interference, the characteristics of full digital operation.
The reverse osmosis controller performs automatic system management, so that the whole system realizes full automatic control and unmanned monitoring, and is adapted to meet pure water equipment and seawater desalination reverse osmosis units in various industries.
Main Technical Specification
For Single Stage Reverse Osmosis System
Collection point of input signal
•Water level of source water tank, this is for checking with or without water. (pipe water supply could be treated as Non-water pressure switch)
•Low pressure pump protection
•One stage high pressure pump protection
•One stage low pressure switch (before one stage high pressure pump)
•One stage high pressure switch (After one stage high pressure pump)
•Second stage high pressure pump protection
•Second stage low pressure switch (before the second stage high pressure pump, WITHOUT middle water tank mode)
•Middle pure water tank Low level (WITH middle water tank mode)
•Middle pure water tank High level (WITH middle water tank mode)
•Second stage high pressure switch (After the second stage high pressure pump)
•Low level of second stage pure water tank
•High level of second stage pure water tank
•Communicate switch of pre-treatment; (system standby when pre-treatment working)
Note: High and low level of pure water tank, such as the duckbill
switch need to install two switches, two switches directly
connected to the high and low liquid level end; if the float switch is used, the high and low liquid level two wires are wired together.
Conductivity measurement
•Source water conductivity : 0～7000μS/cm or 0-3500ppm, shift to display
•Conductivity of RO production water : 0～200μS/cm or 0-100ppm, shift to display
•Second stage RO water conductivity : 0～200μS/cm or 0-100ppm, shift to display
•Temperature measurement : 0-60℃
•Conductivity sensor : 1.0cm-1, cable length 4.5m
