3.6.2 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 section
3.3.2.
Refer to this section and connect the interfaces with the external equipment.
(1) Digital input interface DI-1
Give a signal with a relay or open collector transistor.

External power
supply 24VDC
200mA or more
(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. (Rated current: 40mA or less, maximum current: 50mA or less,
inrush current: 100mA or less)
(a) Inductive load
Servo amplifier
Note. If the voltage drop (maximum of 2.6V) interferes with the relay operation, apply high voltage (up to 26.4V) from external
source.
Servo amplifier
VIN
SON, etc.
R: Approx. 4.7k
