The Oakton WD-56700-10 Eutech pH190 Controller/Transmitter has a 1/8 DIN-sized housing, LED display and two set points, and single pole double throw (SPDT) output relay with on/off control. A pH/oxygen reduction potential (ORP) controller/transmitter is used to measure pH, mV and temperature of a substance in various types of water control, such as fish ponds, and acid and/or base feed in aquaculture. This controller features a scrolling, 14-segment LED display to guide set-up functions and display indicators. It has manual or ATC, and push-button operation with calibration at two set points for ease of use. The controller has a universal power supply from 85 to 250V AC/DC to withstand electrical fluctuations, and it has removable terminal strips to ease field setup. Its 1/8 DIN-sized housing includes mounting hardware for ease of use and installation. It has output control of two SPDT relays at 120 VAC, 6 A max, 240 VAC, 3 A maximum. It has two galvanically isolated current outputs of 4 to 20mA, 200 O max load for remote monitoring or hard copy recording. It has two-level password protection for security, and removable terminal strips for ease of connections. The WD-56700-10 controller has two independently programmable hysteresis bands to prevent rapid contact switch at either set point. It has a water-resistant, Ingress Protection (IP) 66-rated housing, for protection against solid objects or liquids.
A controller/transmitter reads parameters, and automatically adjusts the solution to the programmed set points. It is used to monitor and control parameters in process water, wastewater treatment, chemical processes, and aquaculture applications.
