What Is the 1747-KY1 Key Set?
The 1747-KY1 is a two-key replacement set from Allen-Bradley, built for SLC 500 processors. If you run SLC 5/03, 5/04, or 5/05 controllers, these keys let you set up and program the processor after the host controller is installed. Losing a key should not stall a production line, and this set keeps your maintenance team ready.
This is a practical spare, not a complex module. It belongs to the SLC 500 series under Bulletin 1747, and it exists for one job: getting you into the controller so commissioning and programming can proceed.

Key Specs That Matter
The two-key count is the headline. One key can live with the panel, the other stays with your lead technician. That simple redundancy cuts the risk of a locked-out processor during a shift change or an emergency restart.
The environmental range is wider than most people expect from a key set. Operation holds from 32 to 140 degrees Celsius, and storage survives -40 to 185 degrees Fahrenheit. In a non-condensing environment, humidity from 5 to 95% is acceptable. That covers most plant floors, unheated cabinets, and warehouse shelves.
Insertion timing matters too. The key goes in after the host controller is installed. Follow that order and you avoid unnecessary handling of a live processor.
Where the 1747-KY1 Fits
SLC 500 systems still run conveyors, pump stations, and packaging lines across oil, gas, and general industrial sites. When a processor needs programming access, a missing key becomes a bottleneck. Keeping a 1747-KY1 set on the shelf is a small investment against unplanned downtime.
It also suits integrators who commission multiple SLC 5/03, 5/04, or 5/05 panels. One spare set travels with the commissioning kit, so a lost key never delays a startup.
Installation and Handling Notes
Install the host controller first, then insert the key. Confirm the processor model matches the SLC 5/03, 5/04, or 5/05 compatibility list before you begin. Store spare keys in a dry, non-condensing location within the stated storage range. Keep them with your controller documentation so the next technician finds them quickly.
Buying Checklist
Before ordering, verify your processor model and confirm you need the 1747-KY1 rather than another SLC 500 accessory. Check that your site conditions fall within the operating and storage ranges listed above. If you are unsure, ask for hands-on technical selection help.
