GuardPLC 8-Digital Inputs and 8-Digital Outputs Module 15

Publication 1753-IN010A-EN-P - October 2005

For connection of a load, the reference pole L- of the channel group must be used.

Although L- at terminals 7 and 12 and at terminals 13 and 18 are connected

internally to L- on the power supply input, it is strictly recommended to use 7 and

12 for outputs 1 through 4 only and 13 and 18 for outputs 5 through 8 only. EMC

testing was performed in this manner.

TIP

Inductive loads can be connected without a protection diode on

the load. However, Rockwell Automation strongly recommends

that a protection diode be fitted directly to the load to suppress

any interference voltage.
