PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1747-SN is a Remote I/O Scanner Module for the SLC 500 series platform. This scanner establishes communication between central SLC 500 controllers and distributed I/O adapters. It functions in distributed architectures requiring remote chassis coordination across plant networks. The module draws 600 mA of backplane current at 5 VDC during standard rack operation.
System designers can configure the unit in either normal mode or complementary mode. Normal mode accommodates up to 16 device connections on the remote I/O link. Complementary mode expands link capacity to support up to 32 device connections. The scanner supports RIO cable runs extending up to 3050 meters across industrial facilities. Integrated noise immunity protects data transmission against severe electrical interference.
