About 1747-AIC
The AB 1747-AIC is an isolated link coupler. 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 with current load of this
isolated link coupler is 0.085 Amps at 24 Volts DC. Moreover, the
AB 1747-AIC 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.
The 1747- Advance Interface Converter (AIC) Link coupler which
allows an SLC 500 fixed style or modular style processor to be
communicated or multiplexed with a programming workstation, DH485
network and compatible devices.
This Link Coupler is a panel mounted device. It has DH485
communication terminal, Peripheral connection and a CPU port. It
also has a LED indicator to provide power supply feedback.
If planning to connect an SLC processor, each processor must be
installed with One (1) Link coupler. This enables the connected
processor to be connected to a DH485 network while allowing
simultaneous communication with a programming workstation through
one of the integrated port.
There are a variety of ways to connect a programming workstation
such a personal computer to the link coupler. The computer may use
the integrated USB port, combined with a 1747-UIC converter and
1747-C13 cable. Through the computer’s RS232 serial communication
port, 1747-PIC may be used combined with 1747-C10 communication
cable. For PCMCIA slot or a computer with 1784-PMCK, 1784.PMC4
communication cable is required. All these communication cable
connect to the link’ coupler’s single peripheral terminal.
To connect the controller to a DH485 communication network, Belden
#3106A or #9462 shielded twisted pair cable is required. DH485 is
designed for daisy chain topology with a maximum length of cable
segments of 1219 m or 4000 ft.
If connected to an SLC 500 processor, the link coupler is power via
the communication port otherwise, an external 24VDC power supply is
required to power the link coupler device.
