Chapter 1. Installation
1.7.5c Wiring a 0/4-20 mA Analog Inputs Option Card (cont.)
Before making any connections, complete the steps in Preparing for Wiring on page 14. Wire the analog inputs as
shown on the label in the rear cover (see Figure 11 on page 26).
Note: The analog inputs option card can be calibrated with the Model XGM868i’s built-in analog outputs. However,
be certain that the analog outputs have been calibrated first. See Chapter 1,
Calibration , in the Service Manual
for the appropriate procedures.
1.7.5d Wiring a Totalizer/Frequency Outputs Option Card
Each totalizer/frequency outputs option card provides two or four outputs (designated as A, B, C, and D) that can be
used as either totalizer or frequency outputs.
Before making any connections, complete the steps in Preparing for Wiring on page 14. Then, wire this option card in
accordance with the connections shown on the label in the rear cover (see Figure 3 on page 6 and Figure 11 on
page 26). Figure 6 shows sample wiring diagrams of a totalizer output circuit and a frequency output circuit. Refer to
Electrical Specifications on page 56 for load and voltage requirements.
