Allen-Bradley 1747-SDN DeviceNet Network Adapter

The Allen‑Bradley 1747‑SDN DeviceNet Scanner Module is the DeviceNet master adapter for SLC 500 controllers, bridging an SLC 500 chassis to a DeviceNet network. As the scanner, it polls up to 63 node‑addressable slave devices and supports a pass‑through configuration to bridge two DeviceNet networks when needed. Installed in a single backplane slot, the 1747‑SDN displays a numeric node address on its front panel to aid commissioning and is configurable with Rockwell Automation tools such as RSNetWorx for DeviceNet or RSLogix 500. The module uses the DeviceNet network’s 24V DC power and employs CIP‑based data exchange to communicate I/O data with connected devices, enabling reliable integration of sensors, actuators, encoders, and other DeviceNet devices into an SLC 500 control system. When planning a deployment, ensure proper bus termination at the DeviceNet network ends and correctly set the node address on the front panel during setup; the 1747‑SDN is catalog number 1747‑SDN, Series C, representing Allen‑Bradley’s legacy DeviceNet scanner solution for SLC 500 systems.
