Product Summary
The 1747-SDN module serves as a crucial interface between your SLC 500 processor and DeviceNet devices. This scanner manages I/O data, configuration, and status information across the network. It supports Polled, Strobe, and Change-of-State messaging for flexible data exchange.
Theme A: Product Procurement & Buyer Guide
Understanding the 1747-SDN Role
This module connects your SLC processor to a DeviceNet network. It scans I/O from up to 63 nodes at 125 Kbps. The 1747-SDN operates in slave mode for simple applications. It also supports pass-through mode to bridge separate networks.
Key Specifications for Selection
This module requires a SLC 5/02 controller or later. For pass-through mode, you need a SLC 5/03, 5/04, or 5/05 processor. The single-slot unit draws 500 mA at 5 Volts DC from the backplane. It also draws 90 mA at 24 Volts DC for network communication.
Environmental and Mounting Details
The module operates from 0 to 55 degrees Celsius. You can mount it on a DIN rail or directly to a panel. It withstands vibration of 5 g at 10-500 Hz. The unit also handles operating shock up to 30 g peak acceleration.
Communication and Configuration Options
You can configure the module for Polled, Strobe, Change-of-State, or Cyclic I/O modes. The pass-through feature replaces older 1770-KFD or 1784-PCID connections. This design simplifies network architecture and reduces hardware costs. The module uses M1/M0 file transfers for processor communication.
Indicators and Diagnostics
The front panel includes two LED status indicators. A Module status LED reports the unit’s operational health. A Network status LED shows the DeviceNet link condition. An LCD display provides module address and error codes for troubleshooting.
Theme D: Expert Technical Evaluation & Performance Review
Network Performance and Capacity
The 1747-SDN supports a maximum of 63 nodes on a single network. It communicates at a data transfer speed of 125 Kbps. This speed provides reliable data exchange for most industrial applications. The module handles both discrete I/O and explicit messaging effectively.
Electrical Isolation and Protection
The module provides 30 Volts circuit isolation between DeviceNet and the backplane. It uses Basic Insulation Type tested at 500V AC for 60 seconds. This isolation protects the SLC processor from network faults. The design meets IEC standards for electrical safety.
Environmental Tolerance and Ruggedness
The unit operates in temperatures from 0 to 55 degrees Celsius. It stores safely in temperatures from -40 to 85 degrees Celsius. The module handles humidity levels from 5 to 95 percent non-condensing. These ratings ensure reliable performance in harsh industrial environments.
Certification and Compliance
The 1747-SDN carries c-UL-us and CE certifications for global use. It meets CISPR 11, Group 1, Class A emission standards. The module has a T5 North America temperature code designation. These certifications confirm its suitability for industrial control systems.
Mechanical Design and Integration
The single-slot module fits into any SLC 500 chassis slot. It uses a 10-pin linear plug for DeviceNet connection. The access door protects the plug and wiring from damage. This design allows for quick installation and secure network connections.
