Elegoo 8/4-Kanal DC 5V Relaismodul mit Optokoppler für MCU-Steuerung

• 5V relay interface board. Each channel pulls 70mA driver current, while the high-current relay itself carries AC250V 10A and DC30V 10A.
• Both a normally open and a normally closed contact come on every relay, and you pick the trigger side — TTL or ground — with a jumper.
• A power indicator is fitted to the board, the 8-way version adds a status LED for each road, and every relay coil gets diode protection.
• Standard interface, so a microcontroller can drive the board directly (Arduino®, 8051, AVR, PIC, DSP, ARM, MSP430, TTL logic).
• Optical isolation on all channels keeps switching safe and holds interference down. Common jobs: MCU control, industrial cabinets, PLC systems, smart home wiring.

Elegoo 8/4 Channel DC 5V Relay Module with Optocoupler

Small board, big number: switching capacity reaches 10A thanks to a high-density P.C. board mounting technique.
UL, CUL and TUV recognized.
The plastic compound was chosen for high temperature work and better chemical solution performance.
Sealed types are available.
A simple relay magnetic circuit keeps mass production inexpensive.

Domestic appliances, office machines, audio gear, automobiles — the list of typical uses runs long.
(Remote control TV receivers, monitor displays, and audio equipment that draws a high rushing current.)
