Allen-Bradley 1747-SDN DeviceNet Scanner Module for SLC 500

Product Overview

The 1747-SDN from Allen-Bradley is a DeviceNet scanner module. It works with SLC 500 controllers. This module uses one DeviceNet port. It supports slave mode operation. It sends messages in poll, strobe, and change-of-state modes. It also supports cyclic I/O and pass-through configuration. This module fits in a single slot. It draws 500 mA at 5V backplane current. It also draws 90 mA at 24V. Two LED indicators show module and network status. An LCD display shows address and errors. The DeviceNet port uses a 10-pin linear plug.

Application Scenarios

This scanner connects SLC processors to DeviceNet networks. It controls up to 63 nodes. Use it in factory automation systems. It works with drives, sensors, and actuators. The pass-through feature bridges two DeviceNet networks. This replaces older 1770-KFD or 1784-PCD connections. It is ideal for upgrading existing SLC systems. The 1747-SDN also works in remote I/O applications. It streamlines data exchange between controllers and devices.
