Publication 1746-IN027D-EN-P - December 2012
Careful wire routing within the enclosure helps cut down electrical noise between I/O lines.
Refer to the SLC 500 Modular Hardware Style User Manual, publication
1747-UM011 , for
recommended wiring procedures for TTL modules.
Limit cable length to 15 m (50 ft) per point for inputs in standard environments.
Refer to Allen-Bradley Programmable Controller Wiring and Grounding Guidelines,
publication
1770-IN041 , for complete information.
ATTENTION: To avoid potential damage to TTL modules, handle them by the ends of the
module, not metallic surfaces. Electrostatic discharges can damage the module. take care
to prevent exposure of terminals or components to electrostatic charges.
