PC817 3.6-24V 2 Channel Optocoupler Isolation Board Driver Photoelectric Voltage Converter Adapter Module  _x005f_x000D_ Feature: _x005f_x000D_ 1. When encountering the need for isolation control and voltage conversion in actual work, this module will be used. _x005f_x000D_ 2. It can realize 3.3V or 5V control 3.6---24V voltage level interface. After the control terminal is turned on, the controlled terminal will also be turned on. _x005f_x000D_ 3. The optoelectronic isolation has strong anti-interference ability. It can drive high-power transistors, MOS tubes and other occasions that require high-voltage drive at its back, and can also directly drive low-power 24V relays. _x005f_x000D_ 4. If it is a pulse signal, please note that the limit of 817 is below 4KHz, please do not use this module for control signals greater than 4KHz, it will not work properly. _x005f_x000D_ _x005f_x000D_ Specification: _x005f_x000D_ Product Size: 37 X 30 X 10mm/1.46 X 1.18 X 0.39" _x005f_x000D_ Output Terminal Signal Voltage: 3.6-24V _x005f_x000D_ Output Voltage Range: 3.6-30V  (The output current depends on the specific situation but the maximum should not exceed 10mA. The total power is certain, and the voltage and current are inversely proportional) _x005f_x000D_ The jumper cap can realize whether the output terminal is high potential output or low potential output. _x005f_x000D_ The 2 817 channels on the board are independent, which can realize simultaneous control of different voltages. _x005f_x000D_ _x005f_x000D_ Note: _x005f_x000D_ 1. Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! _x005f_x000D_ 2. Please allow 1-3mm measuring deviation due to manual measurement. _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Included: _x005f_x000D_ 1 X Voltage Isolation Board 1.
