Item Type: Voltage Control Adapter Module_x000D_ Material: Copper Clad Laminate_x000D_ Drive Port Signal Voltage: 3.6-24V_x000D_ Output Port Voltage Port: 3.6-30V_x000D_ Center Distance of Mounting Hole: Approx.42x32mm/1.7x1.3in 1The jumper hat of the voltage control adapter module can realize the high potential or pull down output of the output port. 2The onboard 4 channels 817 are independent, which can realize different voltage control at the same time. 3This product has effective photoelectric isolation and strong anti interference ability. 4It can drive high voltage driving applications such as high power transistors and MOS tubes, and also directly drive low power 24V relays. 5If the voltage control adapter module is a pulse signal, please note that the limit of 817 is 4KHZ or less. 6If the control signal is greater than 4KHZ, please do not use this module, otherwise it will not work normally.The input port is shared with GND;_x000D_ The output ports are independent of each other;_x000D_ It is the output of the optocoupler. After inputting a valid signal in the input port, V and G will be connected.1 x Voltage Control Adapter Module
