Allen-Bradley 1747-AICR Isolated Link Coupler
The Allen-Bradley 1747-AICR is an isolated link coupler designed for Allen-Bradley SLC 500 programmable controller systems. It provides a reliable shielded twisted-pair communication interface for the Data Highway 485 (DH-485) network, enabling secure and stable data exchange between controllers, operator interfaces, and programming devices. This model requires a nominal 24 VDC external power supply source with a current load of 0.085 A.
Network Isolation and Interface
The unit acts as a physical communication junction that protects sensitive controller ports from electrical noise, voltage transients, and ground loops commonly found in industrial plant floors. It features multi-port connectivity, allowing simultaneous access for network trunk lines, CPU connections, and handheld or PC-based programming terminals.
Power Requirements and Wiring
Powered externally via a 24 VDC source, the module maintains a low operational current draw of 0.085 A. Wiring to the DH-485 network utilizes standard shielded twisted-pair cabling, such as Belden 3106A or 9842, to ensure signal integrity over extended factory automation network distances.
