terminated DI modules; Figure 3-9 shows field wiring assignments
associated with remotely terminated DI modules. Figure 3-10 shows
an optional remote termination module with built-in discrete relay
module that supports input from 120 Vac DIs. The special remote
termination module (with built-in discrete relay module) interfaces
with an externally sourced DI module.
