2-4 Overview of the DH-485 Network
1747-AIC Isolated Link
Coupler for DH-485 Use the isolated link coupler (1747-AIC) to connect SLC 500 family devices to
the DH-485 network (as shown on page 2-5). The coupler provides a
6-position removable terminal block for connection to the DH-485
communication cable.
To establish network connections for:
• SLC 500 controllers (SLC 5/03 and below), use a 304.8 mm (12 in.)
cable, supplied with the link coupler (catalog number 1747-C11).
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 communications cable and the attached SLC 500 controller and
peripheral devices.
