1 optical coupling isolation module

5.0 pitch screw terminal is convenient for wiring

The default input optocoupler terminal voltage is 5V. In addition, 12V -30V voltage input can be ordered to contact the shopkeeper

(If there is no indication and no wangwang contact, according to the default delivery).

This board role

1 MCU output level to drive the motor motor and other perceptual devices to do isolation function anti-interference protection MCU part of the circuit.

2 MCU output level is low, the driven module driving voltage is high for level matching such as some PLC input to 24V voltage can be used to convert this module

3 Used for inverter, can invert the input signal output

For example, if the output signal level of a sensor is 12V and the voltage of a single chip microcomputer is 5V, this module can be used for isolation and detection.

5 current amplification, such as MCU output current is too small to drive some circuits, you can use this module for amplification

.
