1.4.2.8 External Contact Input : DI
▶ Before starting external contact output : DI wiring, be sure to turn off the system,
or else you will get an electrical shock.
▶ For the external contact, use a no-voltage contact(including relay contact) that can operate
appropriately under the terminal voltage for a close contact(approximate.. 5V) and the current for a
opened contact(approximate.. 1mA).
▶ When using an open collector, select one with the 2V or less voltage for the closed contact, and 100μA
or less leakage current for the open contact.
