1746-N3 | Allen-Bradley SLC 500 32-Point I/O Module Connector Kit

The 1746-N3 connector kit is designed to facilitate secure and efficient wiring connections between 32-point I/O modules and external wiring in the SLC 500 system. It provides a physical interface that ensures proper electrical contact and robust mechanical connection. This is especially important in industrial applications where stable signal transmission is essential. The kit includes a 40-pin keyed socket header and 45 crimp-type contacts for easy wire termination. Its design helps reduce wiring complexity and supports organized panel layouts.

The connector kit supports 24 AWG wires, which are standard in control applications for low-current signal transmission. These wires are crimped into the socket contacts provided with the kit. The use of 24 AWG ensures optimal electrical performance while remaining flexible enough for efficient routing. Crimped connections are preferred in industrial environments for their vibration resistance and longevity. The wire insulation must also be compatible with the specified contact design.

Yes, the 1746-N3 connector kit carries UL and CE certifications, confirming that it meets key safety and performance requirements. These certifications ensure that the product has passed rigorous testing for electrical integrity, mechanical robustness, and environmental durability. UL certification ensures compliance with North American standards, while CE conformity indicates compliance within the European Economic Area. Using certified components contributes to overall system reliability and safety.

No, the 1746-N3 is specifically designed for SLC 500 32-point I/O modules. Its 40-pin keyed socket and contact arrangement are matched to the pin layout and signal requirements of these modules. Using it with incompatible modules could lead to incorrect connections, signal failure, or physical damage. For other module types (e.g., 16-point I/O), different connector kits or terminal blocks are recommended. Always verify compatibility using the official Allen-Bradley product manuals.

The 1746-N3 is designed for panel mounting. This means it can be fixed securely to a backplane or panel surface, often using screws or mounting brackets. This method ensures the connector remains stationary during operation and maintenance, which minimizes the risk of accidental disconnection. Proper mounting also aids in organized cable management and efficient troubleshooting. Mounting should be done in a dry, protected enclosure as per standard control panel practices.
