WPH/WDP400 Series The WPH/WDP400 Series pH/ORP on-line process controllers are designed for a broad range of industrial, commercial, and municipal water treatment applications. WPH/WDP controllers are easily configured to accurately measure pH or mV (ORP) values from Walchem’s WEL and WDS differential combination electrodes, or any conventional combination electrode. A versatile output configuration allows you to program up to four outputs in a variety of control modes. Select from on/off mechanical relays or pulse proportional control for direct connection to metering pumps. The easyto-use menu format and pre-wired, pre-mounted panel system options make set-up and installation quick and simple. Integrated datalogging is available to validate system performance. A USB memory stick is all that’s needed to extract data and event logs that include electrode measurements, temperature and relay status. Download log files from the USB stick to a PC at your convenience. It couldn’t be easier! Summary of Key Benefits Dual Input Reduces Cost Dual pH or ORP electrode inputs allow one controller to take the place of two, reducing cost and space requirements, and simplifying installation. Versatility for a Broad Range of Applications Select from pH or ORP measurements and from five output options. Use In-Range to control a solenoid valve to dump a batch treatment tank when measurement value is within limits, or program for Out-ofRange Alarm in waste treatment applications when the measurement value is too high or low. Ideal for Harsh Environments The NEMA 4X enclosure, combined with Walchem’s WEL and WDS electrodes, provides a waterproof system with no BNC connectors exposed to wet or corrosive environments. Walchem integrates its advanced sensing, instrumentation, fluid pumping and communications technologies to deliver reliable and innovative solutions to the global water treatment market. Our in-house engineering is driven by quality, technology and innovation. For more information on the entire Walchem product line, visit: www.walchem.com 180459.I May 2014 Walchem, Iwaki America Inc.
