(2) I/O interfaces
(a) Digital input interface (DI)
Give a signal with a relay or open collector trans istor. Refer to section 3.7.3 for the source input.

(b) Digital output interface (DO)
A lamp, relay or photocoupler can be driven . Install a diode for an inductive load, or ins tall an inrush
current suppressing resistor for a lamp load. (Permissible current: 40mA or less, inrus h current: 100mA
or less) A maximum of 2.6V voltage drop occur s in the servo amplifier.
Refer to section 3.7.3 for the source output.

(Note)
Note. If the voltage drop (maximum of 2.6V) interferes with the relay operation, apply high
voltage (up to 26.4V) from external source.
