The Allen-Bradley 1771-RK is a discontinued accessory designed for use with 1771 I/O racks in PLC-5 systems. This package includes 36 keying bands, which are used to prevent the incorrect insertion of I/O modules by mechanically restricting the slot based on module keying. These keying bands help maintain system integrity and reduce the risk of damage or misconfiguration during installation or maintenance. Ideal for use in legacy automation setups, the 1771-RK simplifies hardware setup and ensures proper module alignment.
