4. Interfaces
This section gives the details of the I/O signal interfaces.
(1) Digital input interface DI-1
Give a signal with a relay or open collector transistor.
Source input is also possible. Refer to (5) in this section.
For use of internal power supply
(Note)
For a transistor
Approx. 5mA

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)
