The jumper cap can be used to determine whether the output port is a high or low output. Photoelectric insulation has strong anti-interference ability. It can drive large rear triodes, MOS tubes, etc., where high voltage guide is needed, also can be used directly to operate a 24V low power relay. This module is used when you need to isolate control during actual work and voltage conversion. If it is a pulse signal, please note that the limit of 817 is less than 3kHz. If the control signal is greater than 3kHz, please do not use this module, it will not work properly. It can realize 3.3V or 5V to control the voltage interface of 3.6-30V. After turning on the control clamp, the controlled clamp is also turned on.
