3.5.3Option Board analog inputs switch settings

The Option Board provides the capability to sample analog temperature and pressure 4-20 mA signals. These input signals are individually configurable for sinking or sourcing current via Option Board switches as described in the tables below (Table 3-33through Table 3-38) and in Daniel drawing DE-21056 (particularly page 3, notes 24, 25, and 28, see Appendix I).

If the analog input is configured for “Source” mode (i.e., powered by the meter), then it must be at the bottom of the loop (stack).
