Series 250 RO controllers
|
The most versitile controller of the ROtrol product line, the Series 250 controller is an exceptional choice for industrial and other high-level filter or membrane technology applications.
Unlike a PLC, the Series 250 controller is supplied complete with all the end devices necessary for the monitoring and control of complex water treatment equipment. This eliminates the unnecessary and costly purchasing of seperate water monitors and controls.
User-friendly field programmable set points are provided to allow the customer the flexibility of adjusting all the time delays and other associated functions. The standard controller features universal AC power, 8 switch inputs, 8 analog inputs, 6 relay outputs, 2 analog outputs, 2 channle flow meter interfaces, and channel TDS/Conductivity. Additionally inputs and outputs are optionally available.
