Allen-Bradley 1747-KY1 Key Set SLC 500 Processor Keys

1747-KY1 Allen‑Bradley Replacement Key Set for SLC 500 Processors

Product Introduction

The 1747-KY1 key set from Allen‑Bradley provides essential replacement keys for SLC 500 series processors. This set includes two keys specifically designed for SLC 5/03, SLC 5/04, and SLC 5/05 models. These keys play a critical role in controller setup, programming, and operational access.

Without the proper key, you cannot change processor modes or perform certain programming functions. Therefore, the 1747-KY1 ensures you always have a spare key on hand. This redundancy minimizes downtime if the original key becomes lost or damaged. Its straightforward design allows quick insertion and removal when needed.

Technical Specifications

The 1747-KY1 key set features a simple but essential design. Its compatibility covers the most common SLC 500 processors.

• Number of Keys: 2 keys per set

• Compatible Processors:

  • SLC 5/03

  • SLC 5/04

  • SLC 5/05

• Insertion Requirement: Insert key after host controller is installed

• Function: Used to install and program compatible controllers

Environmental Ratings:

• Operating Temperature: 32 to 140°C (89.6 to 284°F)

• Storage Temperature: -40 to 185°F (-40 to 85°C)

• Non‑Condensing Relative Humidity: 5 to 95%

Additionally, the 1747-KY1 keys are built with durable materials that withstand regular use. Their compact size makes them easy to store in a tool kit or control panel enclosure.

Usage and Installation

Using the 1747-KY1 key set is straightforward. First, ensure your SLC processor is properly installed in the chassis. Then, insert the key into the designated key switch on the front face of the processor.

The key position determines the processor's operating mode. For example, you can set the processor to RUN, PROGRAM, or REMOTE mode depending on your task. Always insert the key after the controller is installed to avoid mechanical interference.

Keep the second key from the 1747-KY1 set in a safe, accessible location. This backup ensures you can quickly restore access if the primary key is misplaced. For security purposes, store spare keys separately from the controller to prevent unauthorized mode changes.

Environmental Durability

The 1747-KY1 keys perform reliably across a wide range of environmental conditions. Their operating temperature range of 32 to 140°C covers most industrial settings. Meanwhile, the storage temperature range of -40 to 185°F allows safe storage in warehouses or maintenance shops.

The keys also tolerate humidity levels from 5% to 95% (non‑condensing). This resilience makes the 1747-KY1 suitable for factories with varying climate conditions. Whether in a dry or humid environment, these keys maintain their mechanical integrity and functionality.

Frequently Asked Questions (FAQ)

Q1: Which processors are compatible with the 1747-KY1 key set?
A1: This key set works with SLC 5/03, SLC 5/04, and SLC 5/05 processors. It does not support SLC 5/01 or SLC 5/02 models.

Q2: Why does the 1747-KY1 include two keys?
A2: The second key serves as a spare. This redundancy prevents downtime if the primary key is lost, damaged, or locked inside a secure enclosure.

Q3: Can I use the 1747-KY1 keys with other Allen‑Bradley controllers?
A3: No, these keys are specifically designed for SLC 500 series processors. They do not fit ControlLogix, CompactLogix, or PLC‑5 controllers.

Q4: How do I insert the key into the processor?
A4: Insert the key into the key switch on the processor's front panel after installation. Turn it to select the desired operating mode (RUN, PROGRAM, or REMOTE).

Q5: What should I do if I lose both keys?
A5: You must purchase a new 1747-KY1 key set. Allen‑Bradley does not offer key duplication services for security reasons.
