Without galvanic\nisolation, interference pulses and voltage spikes can damage the\nmicrocontroller or trigger unwanted switching processes. The set of four\n1-channel optocoupler PC817 modules works with 3V to 5V input voltage and\nswitches output voltages up to DC 24V. Each module is equipped with a PC817\nchip that separates control and load side potential-free. This prevents\nreactions and protects sensitive components. Wiring is done via integrated\n5.0mm screw terminals. Incoming signals are neatly transmitted to the output,\nwith the maximum signal frequency being around 5 kHz. This is sufficient for\nmany switching, control and control applications in the hobby and professional\nsector. As the four boards work independently, different voltages can be\ncontrolled at the same time. In addition to the pure isolation function, the\noptocoupler module can also be used when the output current of a controller is\nnot sufficient - it then acts as a driver stage. Each module undergoes a\nfunctional test before shipping. With four identical units, redundancy and\nflexible project design are possible - for secure signal resolution and\nlasting protection of your control electronics.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eGalvanic isolation for clean signals: The 1-channel optocoupler PC817 reliably isolates control and load circuits and protects microcontrollers from interference caused by inductive loads such as motors or relays - ideal for signal resolution in automation projects.\u003c\/li\u003e\n         \u003cli\u003eFlexible voltage range 3-5V input: the module operates with an input voltage of DC 3V to 5V and outputs an output voltage up to DC 24V. This makes it easy to adapt 3.3V or 5V systems to higher voltages.\u003c\/li\u003e\n         \u003cli\u003eSignal transmission up to 5 kHz: The optocoupler isolation module processes switching and control signals with frequencies up to about 5 kHz. It is suitable for slow to medium speed control tasks, level adjustment and noise suppression on the signal line.\u003c\/li\u003e\n         \u003cli\u003eCompact design with screw terminals: Each of the 4 boards has 5.0 mm screw terminals that allow low-tool and secure wiring. The modules can be used individually and can be mounted to save space in control cabinets or on top hat rails.\u003c\/li\u003e\n         \u003cli\u003eVersatile  also as a driver: In addition to isolating function, the PC817 model can also serve as a power amplifier, such as when the output of a microcontroller is too weak to drive transistors or small loads.\u003c\/li\u003e\n  \u003c\/ul\u003e","brand":"InYoHui","offers":[{"title":"Default Title","offer_id":44374928916660,"sku":"de-B0H1GDFPFF","price":123.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/9906\/1172\/files\/de-B0H1GDFPFF.jpg?v=1788268844","url":"https:\/\/auspowers.com\/products\/optocoupler-pc817-4-pieces-1-channel-3-5v-signal-transmission-up-to-5-khz-compact-design-with-screw-terminals-for-automation-projects","provider":"AusPower Australia","version":"1.0","type":"link"}
