ROS-8600 Touch color screen RO control system

Character & Application The ROC-860 touch color screen RO control system is a multi function controller with combination of resistance- type touch screen + PLC program control and inline conductivity measuring,it is designed for the system control and water quality testing of reverse osmosis system. 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 very easy. The instrument is available in two versions, single stage control system and double stage control system, the RO controller could monitor the conductivity of raw water, first stage production water, second water production water at same time. With 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 RO 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. Main Technique Specifications
