ROSC-8610 Touch Color Screen Reverse Osmosis Control System is a multifunction controller with combination of resistance-type touch screen + PLC program control and online conductivity monitor, it is designed for the system control and water quality testing of reverse osmosis system.
The instrument is with 7 inch big touch screen, 16:9 display rate, 65536 color resolution ration, rich and dynamic display making human-computer information interaction easy.
PLC control and conductivity collection circuit: update American high speed MCU computer processing system, control the outside IO input and relay output in real time, the system is well designed and considered the high stable, high reliable, anti-interference, full digitalization.
The display content of the interface are mainly: conductivity value monitoring interface, system input signal monitoring, output state display, dynamic system process chart, manual controlling interface, setting interface etc. follow the process state of system in real time, which making people could completely control the whole system easily.
The instrument is available in two versions: single stage RO control system and double stage RO control system, the reverse osmosis controller could monitor the conductivity of source water, first stage production water, second stage water production water at same time. With isolated 4-20mA output and RS232 communication system (RS232 adopt MDBUS RTU communication agreement), making the communication between instrument and computer, PLC remote communication and internet.
The single stage reverse osmosis control system making the complete system realize automatic control and unattended monitoring. It could be widely used for pure water equipment, seawater desalination, reverse osmosis system in many industries.
RS232 interface, standard Modbus communication agreement(RTU), which make it can be easily connected with PLC. PC could send out read instruction, then read inlet conductivity value, outlet conductivity value and relay control status.
