4.5.3 Connecting the Multiplexer Devices to the Termination Board
The device is connected to the termination board via a 26-pin ribbon cable. The device has a
26-pin IDC socket on the front of the device for this purpose. 16 cables are intended for
the HART signal of the analog measuring circuits of the field devices. The remaining 10 cables
are connected to ground. For the assignment of the IDC socket, see chapter 9.2.
Pepperl+Fuchs provides special termination boards. Various connection options are available
for these termination boards.
