817 Optocoupler 4 Channel Voltage Isolation Board Voltage Control Switching Module Optical Isolation Module 3.3V 5V

Features This module is used when the actual operation requires isolation control and voltage conversion It can realize 3 3V or 5V to control the interface of 3 6 24V voltage level After the control terminal is turned on the controlled terminal will also be turned on Photoelectric isolation has strong anti interference ability Can drive big behindPower triodes MOS tubes etc where high voltage driving is required can also directly drive low power 24V relays If it is a pulse signal please note that the limit of 817 is below 4KHZ If the control signal is greater than 4KHZ please do not use this module it will not work properly Through the jumper cap can achieve whether the output is high potential output or low output The 4th and 817 on the board are independent which can realize simultaneous control of different voltages etc Specifications The drive terminal signal voltage 3 6 24VThe output voltage range 3 6 30V output current depends on the specific situation but the maximum is not 10MA the total power is certain the voltage and current are inversely proportional Board size Length 48mm Width 38mm Long side hole distance 42mm Wide side hole distance 32mm Package Included 1 x 817 Optocoupler 4 Channel Voltage Isolation Board
