3.4.2 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.
(1)Digital input interface DI-1
Give a signal with a relay or open collector transistor.
