3.6.2 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 3.3.2. 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. Source input is also possible. Refer to (6) in this
section.
For use of internal power supply

Note: This also applies to the use of the external power supply.
(2) Digital output interface DO-1
A lamp, relay or photocoupler can be driven. Provide a diode (D) for an inductive load, or an inrush
current suppressing resister (R) for a lamp load. (Permissible current: 40mA or less, inrush current:
100mA or less)
