Description
Product Overview
The Allen-Bradley 1747-KY1 is a replacement key set designed specifically for the SLC 500 modular processor family by Rockwell Automation. Functioning as the physical access key for the front-panel keyswitch, it allows system operators and engineers to toggle CPU modes between RUN, REM (Remote), and PROG (Program) on modular programmable logic controllers.
Supplied as a set of two (2) keys, the 1747-KY1 ensures immediate operational access and spare redundancy for control cabinets. Weighing an ultra-lightweight 0.04 kg (0.09 lbs) with a packaged shipping weight of 0.15 kg (0.33 lbs), it is fully compatible with SLC 5/03, SLC 5/04, and SLC 5/05 controllers operating across standard industrial environmental ranges.
Core Technical Advantages
- Universal SLC Processor Fit: Standardized key pattern built for direct compatibility with all modular SLC 500 CPUs featuring front-panel keyswitches (SLC 5/03, 5/04, and 5/05).
- Two-Key Redundancy Package: Ships as a pair of identical keys to allow one primary cabinet key and one backup copy for site security management.
- Complete Mode Switching Control: Enables secure manual switching between RUN (logic execution), REM (software control), and PROG (program download/clear) modes.
- Industrial Environmental Durability: Rated to withstand ambient cabinet operating temperatures from 0°C to 60°C (32°F to 140°F) and non-condensing relative humidity up to 95%.

Installation & Handling Guidelines
- Key Insertion Order: Insert the 1747-KY1 key into the processor keyswitch after the host controller is fully mounted into the SLC 500 chassis.
- Mode Verification: Turn key to REM position for standard remote operations via RSLogix 500, or to RUN to lock out online editing during production.
- Key Retention: Store the secondary key in a secure facility location to prevent unauthorized CPU mode changes or loss of access.
