【4 Channel Isolation】This optocoupler isolation board features 4 independent 817 channels, allowing different voltage control at the same time for relay, transistor, and MOS tube applications.
【Wide Voltage Range】Driver port signal voltage supports 3.6V to 24V, while output port voltage supports 3.6V to 30V, suitable for signal conversion and voltage control tasks in control circuits.
【Photoelectric Isolation】The photoelectric isolated module helps reduce interference between input and output sides. After a valid input signal, V and G on the output side will be connected.
【Board Structure】Made of copper clad laminate with mounting hole center distance about 42 x 32 mm 1.7 x 1.3 in. Input port shares GND, while output ports remain independent from each other.
【Application Notes】Designed for high power transistors, MOS tubes, and low power 24V relays. The 817 optocoupler has a 4kHz pulse signal limit, suitable for industrial control and DIY projects.
