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 whose photocoupler anode side is input terminal. Transmit signals from source (open-collector) type
transistor output, relay switch, etc.

*1 It will be approximately 4.3 k for interface of CN3-1 and CN3-10 pins.
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.
