Configured for Universal Remote I/O data exchange in SLC 500 control platforms, the Allen-Bradley 1747-ASB (1747-ASB Remote I/O Adapter Module) provides direct physical/electrical execution between remote I/O racks and SLC processor systems.

Module Identification

The 1747-ASB is a SLC 500 Remote I/O Adapter Module designed to interface remote chassis I/O data through the Universal Remote I/O network. The module supports selectable communication rates of 57.6, 115, and 230 kilobits/second and uses Belden 9463 cable for network connection.

Hardware Specifications

Ethernet/IP and Backplane Communication Characteristics

The Allen-Bradley 1747-ASB operates as a Remote I/O interface component within the SLC 500 modular architecture. The module transfers remote I/O status and control data through the Universal Remote I/O communication network while maintaining local chassis communication through the SLC backplane.

The SLC 500 platform uses modular I/O density scaling through chassis-based expansion. The 1747-ASB allows distributed I/O assemblies to exchange field signal data with the processor system without requiring direct local chassis installation.

Network Interface and Configuration

The module supports multiple Remote I/O communication speeds to match system network requirements. Node addressing and communication parameters must be configured according to the SLC 500 controller architecture and Remote I/O network design.

The 6-Pin Phoenix Connector provides the physical interface for Remote I/O wiring. Cable routing should maintain separation from high-voltage conductors to reduce electrical interference during signal transmission.
