I/O Module Installation and Wiring - I/O Terminal Block Wiring Diagrams

DC Input Module Wiring

The DC Input Module has sixteen inputs, in two groups of eight inputs per group. The groups are isolated from each other; inputs are non-isolated within each group. An example of Digital Input Module wiring is shown in Figure 38. Specifications for this module and for other modules are given in the Specifications section of this manual.

Shield Grounding

Shields must be grounded as described under Shield Grounding at the beginning of this section.

Common Terminals

Two common terminals are provided for each group of eight inputs. Terminals 9 and 10 are connected in the input module, and terminals 11 and 12 are connected in the module.

Jumper Comb

A two-position jumper comb is available (as an option, for barrier-style terminal blocks only) for connecting digital common wiring (at terminals 9 and 11 or 10 and 12). See Figure 39.

Hazardous voltages exist at terminal blocks.

•Using switches at field devices, disconnect the field wiring from power sources before servicing.

Failure to comply with these instructions could result in death or serious injury.
