In automated\nsystems or when working with microcontrollers such as Arduino and PLCs,\nprotecting sensitive components is crucial. The PC817 photocoupler is\ngalvanically isolated to ensure that high voltage circuits and logic circuits\nremain physically isolated from each other, greatly increasing the operational\nreliability of your projects. This module is often used in industrial controls\nwhere 24V sensor signals must be converted into 3.3V or 5V logic level. Even\nwhen controlling inductive loads such as motors or relays, the insulator\neffectively protects the single-chip microcomputer from electromagnetic\ninterference and reverse voltage. Thanks to the sturdy screw terminals in the\n5.0 grid, installation is done quickly without soldering in control cabinets\nor on experiment boards. The set contains 4 pieces of green insulation boards.\nThe input voltage is optimised to 24V DC, while the output voltage can be\nflexibly selected between 1.8V and 24V DC. With an insulation voltage of over\n3000V and a wide working temperature range from -55 to 110 degrees Celsius,\nthe module is designed for demanding environments. FAQ - Frequently Asked\nQuestions What is the maximum frequency for pulse signals? The module supports\na signal frequency of up to 5 kHz. For applications within this range, it\nprovides efficient signal conversion. Can the module be used for power\namplification? Yes, if the output current of a microcontroller is too low to\ndirectly control certain circuits, this module can be used to amplify the\nsignal provided the output current does not exceed 50mA. Is the polarity\nselectable at the output? With the help of the integrated jumper cap, you can\nflexibly adjust whether the output terminal outputs high potential or low\npotential.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n \u003cul class=\"a\"\u003e\n \u003cli\u003eMAXIMUM PROTECTION FOR CONTROLLERS: Are you worried about expensive motherboards in case of power surges? This optocoupler isolation module creates a physical barrier of over 3000V between highly sensitive microcontrollers such as Arduino or PLC and your power devices.
