Source I/O Interface - Mitsubishi Electric MELSERVO-J4 Series Instruction Manual

Source I/O interface

In this servo amplifier, 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 source (open-
collector) type transistor output, relay switch, etc.

Digital output interface DO-1
This is a circuit of emitter output terminal of the output transistor. When the output transistor is turned on, current will be
applied from the output to a load.
A maximum of 5.2 V voltage drop occurs in the servo amplifier.
