1 optikai csatolás leválasztó modul /EL817/PC817/ fotoelektromos leválasztó/optikai csatoló/koksz vezetősín konzol
1 optical coupling isolation module /EL817/PC817/ photoelectric isolator/optical coupler/coke guide rail bracket
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
.

Maximum input current 50MA
Operating current >1MA
Maximum output current 50MA (required input current in 15-20mA)
Working temperature -55~110 degrees.
Maximum application signal frequency: 5KHz
