3-1-4 Interfaces

The details of the interfaces (refer to I/O Division in the table) to the signals indicated in Section 3-
1-2 (4) are given below. Refer to the following and connect the interfaces with the external equip-
ment.
(1) Digital input interface DI-1
Give a signal with a relay or open collector transistor.
Source input is also possible. Refer to (7) in this section.

(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 resistor (R) for a lamp load. (Permissible current: 40mA or less,
inrush current: 100mA or less)
