3.6 Interface
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 source (open-
collector) type transistor output, a relay switch, or others.
*1 It will be approximately 4.3 kΩ for the interface of CN3-1 pin, CN3-10 pin, and CN3-19 pin of the MR-J5-_G_-RJ.
It will be approximately 4.3 kΩ for the interface of CN3-16 pin, CN3-45 pin, and CN3-50 pin of the MR-J5-_A_-RJ.
It will be approximately 4.3 kΩ for the interface of CN3-7 pin, CN3-9 pin, CN3-15 pin, and CN3-22 pin of the MR-J5W_-_G.
*2 It is 500 mA for the MR-J5-_A_.
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.
