3.9.3 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 whose photocoupler anode side 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 side of the output transistor is the output terminal. When the output
transistor is turned on, the current flows from the output terminal to a load.
A maximum of 2.6 V voltage drop occurs in the servo amplifier.

If polarity of diode is
reversed, servo amplifier
will malfunction.
Note. If the voltage drop (maximum of 2.6 V) interferes with the relay operation, apply high
voltage (maximum of 26.4 V) from external source.
