Figure 3-3 shows a typical voltage signal input. Terminal B is the “+” signal input and terminal C is the
“-” signal input. These terminals accept a voltage signal in the 0 to 5 volt range. Since terminal C
connects to a signal ground (non-isolated), the analog input must be a single-ended. Ensure that no
scaling resistor (R1) is installed when the module is used to sense a voltage signal.
