3.8.3 Source I/O interfaces

In this servo amplifier, source type I/O interfaces can be used.
(1) Digital input interface DI-1
This is an input circuit in which the anode of the photocoupler is the input terminal. Transmit signals from
source (open-collector) type transistor output, relay switch, etc.
(2) Digital output interface DO-1
This is a circuit in which the emitter of the output transistor is the output terminal. When the output
transistor is turned on, the current will flow from the output terminal to a load.
A maximum of 2.6 V voltage drop occurs in the servo amplifier.

Note 1. If the voltage drop (maximum of 2.6 V) interferes with the relay operation, apply
high voltage (maximum of 26.4 V) from an external source.
2. For the servo amplifiers manufactured in April 2016 or earlier (or manufactured in
China in May 2016 or earlier), the value 100 mA is applicable.
