1.7.6 Wiring a 0/4-20 mA Analog Inputs Option Card (cont.)
Wire the analog input terminal block in accordance with the pin number assignments shown in Figure 10 on page 16.
If the flowmeter system includes additional transmitters, the Model DF868 can accommodate up to three more analog
inputs option cards. These option cards are identical to the temperature card described on page 12 and they should be
wired in the same manner (see Figure 10 on page 16).
The analog inputs on the option card(s) can be calibrated with the Model DF868'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.

1.7.7 Wiring a Totalizer/Frequency Outputs Option Card

The Model DF868 can accommodate up to four totalizer/frequency outputs option cards. Each totalizer/frequency
outputs option card provides four outputs (designated as A, B, C, and D) that can be used as either totalizer or
frequency outputs.
Each totalizer/frequency output requires two wires. Wire this terminal block in accordance with the pin number
assignments shown in Figure 10 on page 16. Figure 8 shows sample wiring diagrams of a totalizer output circuit and a
frequency output circuit.
