Walchem’s W600 Controller still has the powerful programming to give you complete control of chemical metering pumps and valves in a broad range of water treatment applications, with a few very valuable updates!

• New combination Sensor Input and Analog Input board that adds even more flexibility
• Modbus/TCP communications
• Graphing capability is now extended to web pages as well as the local display
• Two Virtual Inputs that are calculated from two real inputs (cycles of concentration, % rejection, etc.)
• PID control using Pulse or  Analog outputs
• On and Off Delays added to some control algorithms
• Lead/Lag control of up to 6 relay outputs
• Intermittent Sampling for boilers without using a trapped sample
• Added a 2nd flowmeter input to the Feed Timer control algorithm
• Antimony pH sensor support
• Ability to restore default settings
• Chinese and Taiwanese languages
• Ability to choose to feed the last missed Biocide after an interlock
• Ability to set the flow total to match the meter’s register 
• Total support for eService Reports 
• Modified Bleed/Feed and % Timer algorithms so a feed cycle doesn’t begin immediately after and interlock clears 
• Improved system stability 
• Improved sensor speed of response
