3.3 Connection of Basic and Extension Modules
Connect I/O modules mounted on the Terminal module A by using 34-pin flat cable connectors
as shown in the figure below. Ensure that all 34 pins at one end of the cable are connected to
the corresponding pins at the other end; e.g., connect the A1 pin to the pin having the same
designation (A1) at the other end.

Flat cable-side connector specification:
HIF3BA-34DA-2.54R (Hirose Electric Co., Ltd.)
Module connector-side specification:
HIF3BA-3403-1202-0BS (Hirose Electric Co., Ltd.) or
FAP-3403-1202-0BS (Yamaichi Denki Co., Ltd.)
Note) Make the length of the flat cable more than 100mm in consideration of wiring to the terminal
blocks on the terminal module A. But, the maximum length of the total extension of the flat
cable is 300mm.
To ensure adequate ventilation, install the modules in such a way that the flat cables lie on
top of them. The basic module has a vent at the top (as indicated by the dotted lines in the
above figure). When connecting modules, install extension modules so that the flat cables
do not cover the vent, as shown in the above figure. Therefore, for direct connection to the
Terminal module A, expansion modules are installed to the right of the basic module on the
installation plane.
