Allen-Bradley 1747-DCM

Overview

The Allen-Bradley 1747-DCM is a Distributed Communication Module (DCM) for the SLC 500 series of programmable logic controllers. It enables remote I/O communication over RS-232 or RS-485 networks, allowing SLC systems to interface with other controllers and I/O nodes in distributed architectures. Ideal for expanding I/O capabilities without centralizing all wiring, this module simplifies system integration across large or remote industrial installations.

Key Features

  • Series: SLC 500

  • Function: Distributed Communication Module (DCM)

  • Interfaces: RS-232 and RS-485 communication ports

  • Application: Acts as a remote I/O adapter or communication bridge

  • Mounting: DIN rail or chassis-mounted

  • Baud Rates Supported: Up to 19.2 kbps

  • Status Indicators: Front panel LED diagnostics

  • Configuration: Through SLC 500 programming software (RSLogix 500)

Technical Specifications

  • Catalog Number: 1747-DCM

  • Communication Type: RS-232/RS-485

  • Supported Protocols: DF1, RIO

  • Power Supply: Draws power from the SLC chassis

  • Backplane Current Draw: 330 mA @ 5V DC

  • Operating Temp: 0°C to +60°C

  • Isolation Voltage: 500V continuous

  • Certifications: UL, CE, CSA

  • Chassis Compatibility: All standard SLC 500 racks

Applications

  • Remote I/O data collection and processing

  • Expanding SLC 500 systems across factory floors

  • Communication interface for distributed PLC systems

  • Industrial automation networks in manufacturing, utilities, and more

  • Bridging legacy systems with modern I/O

Why Choose the 1747-DCM

  • Allows efficient remote I/O control for large installations

  • Seamless integration with existing SLC 500 systems

  • Supports multiple network topologies via RS-232/RS-485

  • Reduces wiring complexity in distributed automation setups

  • Allen-Bradley quality and reliability for mission-critical environments
