Product Overview
Unused Allen-Bradley 1747-SCNR SLC Controlled Scanner in Manufacturer’s Packaging
The Allen-Bradley 1747-SCNR SLC Controlled Scanner is a communication expansion module designed for the SLC platform, providing additional connectivity through the 1746 backplane. Installed in a single chassis slot, it supplements the communication ports available on SLC processors and improves data exchange across distributed systems.
This unit is unused, kept in its original manufacturer’s packaging. The box shows storage wear and was opened for inspection and photos only.
Product Condition
Unused, kept in manufacturer’s packaging. Packaging shows wear from storage. The module was opened for inspection and photography only and remains in excellent preserved condition.
Product Overview
Allen-Bradley’s 1747-SCNR module expands communication capabilities for SLC controllers by adding scanner functionality through the 1746 backplane. It includes a node address and status display, Channel A and B indicators, and a module status LED for quick diagnostics. Although formally discontinued at the end of 2015, it remains an essential replacement part for maintaining legacy SLC installations that rely on additional communication ports.
Professionals in industrial automation value the SCNR module for its reliability, integration simplicity, and continued importance in long-lived SLC systems still operating across manufacturing, utilities, and process plants.

Frequently Asked Questions
Is this module compatible with standard SLC 1746 chassis?
Yes. The 1747-SCNR installs into a single slot of a 1746 chassis and communicates over the backplane.
What communication indicators does it provide?
It includes Channel A and B status LEDs, a module status indicator, and a node address/status display.
Is the unit unused?
Yes. It is unused and was kept in its original manufacturer’s packaging, opened only for inspection and photos.
Is this model still produced?
No. It was discontinued in 2015, making remaining unused units important for maintaining legacy SLC systems.
Who typically uses this module?
Control engineers, maintenance teams, and integrators responsible for supporting SLC-based machinery and communication networks.
Rockwell’s 1747-SCNR served for years as a quiet backbone in SLC communication systems. Preserved in its packaging, this unused module is ready to keep a legacy installation running where continuity still matters.
