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).

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.

The following types of expansion cables are available.

For details on the specification of I/O modules, see 2.3, I/O

module specifications.

Carefully read the Cautions described In Section 3 for applying I/O modules.

The I/O module can be mounted in any I/O slot functionally.

However, to improve noise-immunity for the entire system, it is recommended to separate the low voltage 1/Os and the power I/Os. (See 4.7, I/O Wiring.)
