3. WIRING
3 - 1 - 3 Interfaces
The details of the interfaces (refer to I/O Division in the table) to the signals indicated in Section 3.1.2 are
given below. Refer to the following information and connect the interfaces with the external equipment.
(1) Digital input interface DI-1
Give a signal with a relay or open collector transistor.
(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)
