Product Details
Description
The Allen-Bradley 1747-DCM is a Direct Communication Module for connecting an SLC 500 controller to a distributed processing system via Remote I/O (RIO) link. It supports communication between I/O adapters and controllers, using Belden 9463 cable for wiring. The module draws 360mA at 5V and dissipates 1.80 watts of thermal power. It features FAULT and COMM LED indicators for easy troubleshooting, with the FAULT LED signaling errors and the COMM LED indicating normal operation. The module requires two addresses: one for the SLC processor and another for the supervisory scanner.
Key Feature
Remote I/O Communication: Enables communication between SLC 500 controllers and distributed I/O systems via Remote I/O (RIO) link.
Belden 9463 Cable: Designed for use with Belden 9463 cable for reliable wiring connections.
Current Consumption: Draws 360mA at 5V DC from the backplane, with 0mA at 24V DC.
Thermal Dissipation: Minimum and maximum thermal dissipation of 1.80 Watts.
Compatibility
SLC 500 Controllers: Designed specifically for SLC 500 Fixed and Modular controllers to enable communication via Remote I/O (RIO) link.
Distributed I/O Systems: Compatible with remote I/O networks for connecting I/O adapters and controllers in distributed processing setups.
Supervisory Controllers: Works with supervisory controllers that manage Remote I/O networks, facilitating data transfer between the SLC 500 processor and the remote I/O devices.
