Mô Đun Chuyển Đổi Cách Ly Quang Điện 4 Kênh Pc817 3.6-30v

Description:
This module is used when it is necessary to isolate the control in actual work and
Voltage conversion.

It can realize 3.3v or 5v control 3.3--30v voltage level interface, after the control
High level input terminal is turned on, the controlled terminal will also conduct to
The ground, and the port changes from the original high level to the low level. For
The friend of the single-chip or plc, it is only necessary to judge when the output
Port is low.

The photoelectric isolation has strong anti-interference violence, and the
Combining control of many different devices can be realized later, such as triode,
Mos tube, and small power relay module.

If it is a pulse signal, please note that the limit of 817 is below 3khz. # if the control #
Signal is greater than 3khz, please do not use this module, it will not work proper.


Parameters:
1, the drive terminal signal voltage: 3.3-24v

2, the output voltage range: 3.3-30v (output current dependents on the specific
Situation, but the maximum is not 10ma, the total power is certain, the voltage and
Current are inversely proportional)

3, through the jumper cap can achieve when the output is high potential output
Or low output.

4, the board above 2 / 4 817 are independent, can achieve simultaneous control of
Different voltages, etc.

5: Board size: Length: 48mm; width: 38mm; long side hole distance: 42mm; wide
Side hole distance: 32mm

Characteristics:
1. It can realize low level driving high level and realize voltage conversion.

2. Using this module, the io voltage of the mcu can be graded to achieve isolated
Drive between different voltage levels.

3. Through the selection of the jumper cap of each channel it is possible to achieve
Separate control when it is shared with the input. The jumper cap is shorted so
That the negative terminal of the output terminal is connected to the negative pole
"G in the figure".

4. Each channel has an independent power indicator, which can be directly driven
By the io port of the mcu The input terminal is 5v high, and the 3-5ma current
Can be driven.


Application:
1. Mcu output level to drive the motor when the inductive device such as the
Motor is isolated, anti-interference protects the circuit of the mcu.

2. The output level of the single-chip microcomputer is low, and the driving voltage
Of the driven module is high. For level matching, for example, some plc input
Should have 24v voltage and can be converted by this module.

3. For the inverter, the input signal can be inverted.

4. Used for high voltage detection, for example: The output signal level of a sensor is
12v. The voltage of the single chip is 5v. This module can be used for isolation
