Photomos relay原理

WebPhotoMOS Relay Technical Information The emitted light passes through transparent silicon and reaches the photoelectric element (solar cell) which is mounted opposite the LED. The photoelectric element converts the received light to a voltage corresponding to the quantity of light. This voltage passes through a control circuit and charges the Webrelay be activated and the load side interrupted until the fault is cleared. Below the development of a normally closed semiconductor relay is described. side. Due to the behaviour of the MOSFETs, a A PhotoMOS relay consists of a light emitting diode (LED), an array of solar cells with a control circuit and two Power MOSFETs. The LED is optically
