1747-DCM | Allen-Bradley | Direct Communication Module

Description

Technical Specifications

The Allen-Bradley 1747-DCM is a Direct Communication Module (DCM) designed specifically for the SLC500 series, catering to Remote I/O applications. It facilitates the transfer of data between Supervisory Processors, such as PLC–5s, and distributed SLC–500 Processors that reside on an Allen–Bradley RIO Communication Link.

This module serves as a critical intermediary for communication between different processors within industrial automation systems. It enables Supervisory Processors and distributed SLC–500 Processors to exchange data seamlessly, enhancing coordination and efficiency in system operation.

The 1747-DCM supports various operation modes, including Standard and non-extended node configurations, ensuring flexibility in system setup and operation. It is compatible with SLC 500 Fixed and Modular style controllers, providing versatility in application across different control architectures.

Equipped with LED indicators for FAULT and COMM, the module offers visual feedback on its operational status, aiding in troubleshooting and maintenance activities. Additionally, it supports terminating resistors of 82 Ohms and 150 Ohms, enabling optimization of communication signals within the network.

For communication connectivity, the 1747-DCM utilizes Belden 9463 or any equivalent communication cable. It supports transmission rates of 57.6K baud at 10,000 feet and 115.2K baud at cable lengths of 5000 feet, ensuring reliable data transmission over extended distances.

The module operates within an operating temperature range of 0°C to 60°C (32°F to 140°F), suitable for deployment in various industrial environments. With a compact design and weighing only 0.37 pounds (168 grams), it offers ease of installation and integration into existing automation systems.

Featuring 6-Pin Phoenix Connectors, the 1747-DCM facilitates secure and stable connections with other components within the network. Its dimensions of 5.72 x 1.37 x 5.15 inches further contribute to its space-efficient design, allowing for flexible placement within control panels and enclosures.
