The 1747-AIC/isolated link coupler is inclusive of the Allen Bradley PLC SLC 500 series. The purpose of this unit is to connect SLC 500 devices to the DH-485 network. It is equipped with 6 position of removable blocks for connecting to the DH-485 communication cable, with the connection cable types being shielded-twisted-pair as well as open type. Installation of a link coupler is necessary for every node on the network.
The 1747-AIC also provides room for additional link couplers in case more nodes are added in the future. The installation of an additional link must be done during the first installation to prevent recabling when the network is in operation.
The length limit for a 1747-AIC communication cable is exactly 1219 meters (4000 feet) and is the full distance between the first and the last nodes on the network. The current load for this unit is 0.085 A at 24 Volts DC (Direct Current), and it can operate at an average temperature range of 32 to 140 degrees Fahrenheit.
The 1747-AIC isolated link coupler provides network connections to an SLC 500 processor that corresponds to the part number 1742-C1 and has 308.4 millimeters as its length.  The standard part 1747-C10, having a cable length of 1.8 meters or 6 feet, supplies network connection to the 1742-PIC, the 1747-DTAM-E and the 1747-PT1. The 1747-AIC has estimated dimensions of 1.5 x 6.8 x 6.5 inches and generally uses a terminal for identification.
The Allen-Bradley 1747-AIC device is an isolated link coupler for the SLC 500 controllers which is used to connect devices from the SLC 500 family to the DH-485 network. The coupler comes with a 6-position RTB (removable terminal block) for DH-485 cable connection. A 12-inch cable supplied with the 1747-AIC coupler (catalog number 1747-C11) is used to provide a network connection for the SLC 500 controller. A 6-foot cable with the catalog number 1747-C10 is required to provide network connections for peripheral devices such as hand-held terminals, data table access modules, and personal interface converters. Up to 1500 Volts DC isolation is provided by the coupler between the cables and connected drives to protect the connected controllers and peripheral devices. The 1747-AIC coupler also provides connectivity for peripheral devices for distances of up to 4000 feet.

The Allen-Bradley 1747-AIC coupler is powered by the controller when it is connected to the controller. If the link coupler is not connected to the controller, then an external Class 2-rated 24 Volts DC power supply is required. The chassis ground terminal on the link coupler must be grounded before it is put into operation. Both the minimum and maximum power draw of the 1747-AIC coupler is 2 Watts. The cable recommended for the DH-485 network connections is Belden #9842 cable. This is a jacketed cable which is shielded and contains 2 twisted wire pairs and a drain wire. One pair of wires is used to provide a balanced line signal. The other wire pair is used as a common reference. The shield on the cable reduces the effect of external noise.
The Allen-Bradley 1747-AIC device is an isolated link coupler. It is used to connect SLC 500 controllers to DH-485 networks and peripheral devices.
