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 using
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.
