186 Setting Up the DH-485 Network
1747-AIC Isolated Link
Coupler for DH-485
The isolated link coupler, catalog number 1747-AIC, is used to
connect SLC 500 family devices to the DH-485 network. The coupler
provides a 6-position removable terminal block for connection to the
DH-485 communication cable.
Network connections for SLC 500 processors are provided by the
1747-C11 cable, supplied with the link coupler. Network connections
for peripheral devices, such as the personal interface converter,
catalog number1747-PIC, or Data Table Access Module, catalog
number, 1747-DTAM-E are provided by the 1747-C10 cable supplied
with each of those devices. If you need to connect a peripheral device
that is between 1.8 m (6 ft) and 6.1 m (20 ft) away, use the 1747-C20
cable.
To protect connected devices, the coupler provides 1500V dc isolation
between the communication cable and the attached SLC 500 controller
and peripheral devices (PIC or DTAM).
The isolated link coupler can also be used to provide connectivity
between a peripheral device (programming software and PIC or
DTAM) for distances greater than 1.8 m (6 ft) up to a maximum of
1219 m (4000 ft). Below is an example of a remote connection
between a computer running your programming software and an
SLC 500 processor.
