About this item
  • EXCELLENT PCB: High-quality PCB materials have reliability and miniaturization, good maintenance and interchangeability
  • DRIVE VARIOUS OCCASIONS: Optical isolation has strong interference-resistant ability, which can drive high-power transistors, MOS tubes and other occasions that require high-voltage drive, and can also directly drive low-power 24V relays to work
  • POWER ON CONTROLLED TERMINAL: Can realize 3.3V or 5V control interface with voltage level of 3.6-24V. After the control terminal is turned on, the controlled terminal will also be turned on
  • SIMULTANEOUS CONTROL OF DIFFERENT VOLTAGES: The 4 channels of the 817 on the board are independent, which can realize the simultaneous control of different voltages, etc.
  • HIGH LEVEL OR PULL-DOWN OUTPUT: Whether the output connection is a high level output or a pull-down output can be realized by the jumper cap
Product description

Specification: Item Type: Optocoupler Isolation Board Material: PCB Drive Voltage: 3.6-24V Output Voltage Range: 3.6-30V (Output current depends on the actual situation, but the maximum output does not exceed 10mA, the total output is constant, voltage and current are inversely proportional) Package List: 1 x Optocoupler Isolation Board Note: If it is a pulse signal, please note that the limit of 817 is below 4KHz. Please do not use this module for control higher than 4KHz, otherwise it will not work properly.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days โ€” so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
