Allen-Bradley 1747-SN/B SLC 500 DH+ Network Interface Module
The Allen-Bradley 1747-SN/B is a high-performance DH+ (Data Highway Plus) network interface module engineered for seamless integration with SLC 500 modular controller systems. This genuine Rockwell Automation component enables robust peer-to-peer communication across distributed control architectures, delivering deterministic data exchange at speeds up to 230.4 Kbps.
Technical Specifications
- Catalog Number: 1747-SN/B
- Series: B Revision
- Network Protocol: DH+ (Data Highway Plus)
- Communication Speed: 57.6, 115.2, or 230.4 Kbps (selectable)
- Maximum Network Nodes: 64 devices per segment
- Backplane Current Draw: 200 mA @ 5V DC, 50 mA @ 24V DC
- Operating Temperature: 0 to 60 °C (32 to 140 °F)
- Mounting: Standard SLC 500 chassis slot
- Certifications: UL Listed, C-UL, CE compliant
Key Applications
This network interface module excels in multi-controller environments requiring coordinated process control, including manufacturing assembly lines, material handling systems, batch processing operations, and SCADA integration projects. It supports MSG instruction-based data sharing between up to 64 SLC processors, PanelView terminals, and RSLogix programming workstations on a single DH+ trunk.
Integration & Compatibility
The 1747-SN/B installs directly into any available slot within SLC 500 chassis (1746 series), automatically recognized by the processor upon power-up. It maintains full compatibility with RSLinx Classic gateway software and integrates with FactoryTalk View SE/ME for real-time HMI data visualization. The module supports both polled and unsolicited messaging modes for flexible system architecture design.
Common Questions
Q: Can I mix different baud rates on the same DH+ network?
A: No, all devices on a DH+ segment must operate at the same communication speed. Configure all nodes to match via rotary switches or software settings.
Q: What cable type is required for DH+ connections?
A: Use Belden 9463 or equivalent twin-axial shielded cable with 1747-C series connectors. Maximum segment length is 10,000 feet at 57.6 Kbps.
Q: Does this module support remote I/O communication?
A: No, the 1747-SN is designed exclusively for DH+ peer-to-peer messaging. For remote I/O, use the 1747-SDN scanner or 1746-ASB adapter modules.
Warranty & Support
Every 1747-SN/B module is backed by our comprehensive 12-month warranty covering manufacturing defects and functional failures. Our technical support team provides configuration assistance, troubleshooting guidance, and replacement coordination to minimize downtime in critical automation environments.
