Description

The Allen-Bradley 1747-SN is a Remote I/O (RIO) Scanner module designed for the SLC 500 programmable controller family. This module enables the SLC 5/02, 5/03, 5/04, and 5/05 processors to communicate with and control remote I/O chassis and other compatible devices over a Remote I/O link. It acts as a scanner, managing data exchange between the processor and remote adapters, ensuring efficient distributed control in industrial automation environments.

Features

• Compatible with SLC 5/02, 5/03, 5/04, and 5/05 processors.
• Supports high-speed data communication over the Remote I/O link.
• Provides seamless integration for distributed I/O architectures.
• Standard SLC 500 form factor for easy rack mounting.
• Power requirement: 5V DC at 600mA.

Applications

This module is typically utilized in manufacturing and process control systems where remote I/O distribution is required to reduce wiring complexity. It is commonly found in legacy SLC 500 installations requiring expansion or replacement of existing RIO communication hardware.

Technical Specifications

Installation Guidelines

• Ensure the SLC 500 chassis power is disconnected before installing or removing the module.
• Slide the module into the designated slot in the SLC 500 chassis and ensure it is fully seated.
• Tighten the mounting screws to secure the module and ensure proper grounding to the chassis.
• Use shielded communication cables for the Remote I/O link to minimize electromagnetic interference (EMI).
• Verify that the Remote I/O link termination resistors are correctly installed at both ends of the link.

FAQ
