DollaTek 5pcs 817 Optocoupler 2-Way Voltage Insulation Board Voltage Control Switch Module

DollaTek 5pcs 817 Optocoupler 2-Way Voltage Insulation Board Voltage Control Switch Module

Module parameters: 1. The drive terminal signal voltage: 3.6-24 V. 2. The output voltage range: 3.6-30V (output current depends on the specific situation, but the maximum is not 10MA, the total power is safe, the voltage and current are inversely proportional). 3. The jumper cap allows you to achieve whether the output is high potential output or low output. 4. The card 2 over 817 is independent, can achieve the simultaneous control of different voltages, etc. Package includes: 5 x modules

Product Features

• This module is used when it is required to isolate the control at actual work and voltage conversion.
• It can realize 3.3V or 5V to control the interface with a voltage level of 3.6 to 24V. After switching on the control terminal, the controlled terminal is also switched on.
• The photoelectric insulation has a strong anti-interference ability. The latter can drive high performance triodes, MOS tubes and other applications that require high voltage, and can also directly drive 24V low-power relays.
• If it is a pulse signal, please note that the limit of 817 is below 4 kHz. If the control signal is greater than 4 kHz, please do not use this module, it will not work properly.
