3.8.3 Source I/O interfaces
In this driver, source type I/O interfaces can be used.
(1) 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.

It will be approximately 4.3 kΩ for interface of CN3-1 and CN3-10 pins.
(2) 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 driver.

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