AB SLC 500 DH-485 LINK COUPLER 1747-AIC SERIES B - OPEN BOX / NEW

About 1747-AIC:

The AB 1747-AIC drive is an isolated link coupler under the AB PLC SLC 500 series. The panel-mountable coupler conforms to the NEMA standard ICS 2-230, IEC1000-4-2, EN50081-2 Class A, and the IEC1000-4-3 regulations and standards. In addition, this device is CSA certified. The dimensions of the coupler are 1.5 x 6.8 x 6.5 inches and it uses a terminal. The current load of this isolated link coupler is 0.085 Amps at 24 Volts DC. Moreover, the AB 1747-AIC drive offers an advanced interface converter with a shielded twisted-pair communication interface. This interface helps with communication between several network devices in the SLC 500 family such as the SLC 5/02, SLC 5/01, and the SLC 5/03 processors and the DH-485 link.

Note that connecting more than 2 SLC500 processors with a DH-485 link requires 1 isolated coupler on the 1747-AIC drive. Also, 1 link coupler should be connected at each end of the link if a computer or DTAM is linked at a distance greater than 20 feet or 6.09 meters. To connect with the processor, an AB 1747-C11 cable is provided with the coupler. To connect to the DH-485 communication cable, the coupler offers a 6-position removable terminal block. The communication cable is 1219 meters or 4000 feet in length. The backplane current of the 1747-AIC is 0 mA at 5 Volts and 85 mA at 24 Volts. The thermal dissipation is 2 W minimum and 2 W maximum, respectively and the relative humidity range of the 1747-AIC drive is from 5 to 95% without condensation. The isolated coupler comes with 1 G operating vibration at 5 to 2000 Hertz operating vibration and 2.5 G non-operating vibration at 5 to 2000 Hertz. For a 24 Volts DC power source, the coupler requires 20.4 to 28.8 Volts DC.
