3. SIGNALS AND WIRING
(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.
(b) 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)
