Source I/O interface
For the servo amplifiers in this manual, source type I/O interfaces can be used.
Digital input interface DI-1
This is an input circuit in which the anode of the photocoupler is the input terminal. Transmit signals from a source (open-
collector) type transistor output, relay switch, etc.

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 flows from the output terminal to a load.
A maximum of 5.2 V voltage drop occurs in the servo amplifier.
