(2) Detailed description of the interfaces

This section gives the details of the I/O signal interfaces (refer to I/O Division in the table) indicated in

Sections 3.2.2.

Refer to this section and connect the interfaces with the external equipment.

(a) Digital input interface DI-1

Give a signal with a relay or open collector transistor.
