Field wiring for one pH sensor input (module ID C)

Figure 14 indicates the recommended wiring for one pH sensor input. Note that two analog input channels are required, one for the pH sensor and one for temperature. Similar wiring may be used for additional sensors. A UMC800 controller can accommodate 2 power modules for a total of up to 8 pH inputs.
