Toshiba Programmable Controller PROSEC T3 - Manual (Page 29)

1. System Configuration
Since there is no compatibility between the standard type and
the long-distance type, these two types cannot be mixed in one
T3 configuration.
The standard type expansion cable and the long-distance type
expansion cable are not compatible with each other. (See
Section 1.7 Expansion Cable.)
If the standard type is used, whether a power supply module is
necessary for the expansion unit will depend on the internal 5
Vdc current consumption. (See Section 1.9 Examining the
power supply capacity.)
For the IF351, change the power supply mode plug as shown in
the figure below (depending on whether a power supply module
has been mounted on its own unit).
IF351
Front
to 1-2 shorted (witii a power supply).
For the long-distance type, a power supply module is needed for
each of the expansion units.
In the long-distance type, the IF312 is for basic unit, the IF352 is
for middle expansion units and the IF353 is for the end
expansion unit.
