Source I/O Interface - Mitsubishi Electric Melservo-Jet MR-JET Series User Manual

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 2.6 V voltage drop occurs in the servo amplifier.

*1 If the voltage drop (a maximum of 2.6 V) interferes with the relay operation, apply high voltage (a maximum of 26.4 V) from an external
source.
