The Allen-Bradley 1747-ASB is a remote I/O adapter module that is part of the SLC 500 system. It establishes a communication link between SLC or PLC scanners and various 1746 I/O modules via Remote I/O. The Remote I/O link consists of one master device i.e., an SLC or PLC scanner and one or more slave devices that are adapters. The SLC or PLC image table gets I/O module image-mapping directly from its chassis. For image mapping, it supports both discrete and block transfer. The 1747-ASB has support for 1/2-slot, 1-slot, and 2-slot addressing with efficient image utilization. It is installed in the chassis with the SLC 500 processor and it scans I/O in the chassis. The 1747-ASB module has 375 mA backplane current at 5V and 0 mA at 24V. It has a minimum and maximum thermal dissipation of 1.875 W. It can communicate I/O data over a distance of up to 3040 meters and it supports 57.6K, 115.2K, and 230.4K baud rates. It allows a user-selected image size of up to 32 logical groups and it controls up to 30 chassis slots. The 1747-ASB also provides non-volatile memory and extended node capability to up to 32 adapters. For wiring, the Belden 9463 or similar category cable must be used, and it does not require any user programming. It uses a 6-Pin Phoenix Connector for connection between the Remote I/O link and the processor. The 1747-ASB module supports all SLC 501 I/O modules like basic modules, resistance modules, high-speed counter modules, etc. For troubleshooting and operation, it has three 7-segment displays with enhanced capability for displaying operating status and errors. The 1747-ASB is intended for use in an Industrial environment and provides a NEMA standard noise immunity.
