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, publicatio
recommended wiring procedures for TTL modules.
Limit cable length to 3 m (10 ft) per point for outputs in standard environments.
Refer to Allen-Bradley Programmable Controller Wiring and Grounding Guidelines,

Relay Contact Modules
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.
WARNING: Exposure to some chemicals may degrade the sealing properties of materials used
in the following devices: Relay Epoxy.
It is recommended that the user periodically inspect these devices for any degradation of
properties and replace the module if degradation is found.
