KEHIPI

KEHIPI 8 Pack 3V 1 Channel Relay Module Optocoupler High Level Trigger ESP8266 Development Board

SKU CH-FTDN-11MCR

Eight 3 V single-channel relay boards with optocoupler isolation switch 10 A loads at 250 V AC or 30 V DC and trigger from a 1.3 V high-level signal

  • Optocoupler isolation protects microcontrollers from load spikes
  • High-level trigger at 1.3 V suits 3.3 V logic directly
  • 10 A switching at 250 V AC or 30 V DC handles mains appliances
  • Sub-20 ms response with 100 000 cycle rating ensures reliable actuation
  • Eight boards included for multi-channel IoT projects

8 Pack 3V Relay Module for IoT Projects

This set contains eight single-channel relay boards designed for 3V or 3.3V logic systems. Each module uses an EL817 optocoupler to isolate the control circuit from the load side. The boards are aimed at makers integrating switching functions into ESP8266, NodeMCU, Raspberry Pi, ARM, PIC, AVR or similar microcontroller projects.

High Level Trigger with 10A Load Rating

The relay activates on a high-level TTL signal of 1.3V, drawing minimal current from the microcontroller IO pin. On the output side each relay handles up to 10A at 250VAC or 10A at 30VDC through normally open, common and normally closed contacts. Response time is under 20ms and the mechanical life is rated to 100,000 operations with freewheel diode protection fitted.

Check Voltage Logic and Mounting Space

Verify that your controller delivers a 3V or 3.3V high-level output compatible with the 1.3V trigger threshold. The board measures 70mm by 17mm by 20mm with a 7.5mm socket pitch, so confirm clearance in your enclosure. Ensure the load you intend to switch stays within the 10A AC or DC limits and that wiring to the screw terminals meets safety requirements for mains voltages.

Kérdések a termékről

Should I choose the 8-pack or buy single modules for my ESP8266 project?

The 8-pack supplies eight identical 1-channel 3V relay boards, each rated for 10A at 250VAC or 30VDC, so you can control up to eight separate circuits from one order.

What does the 10A 250VAC rating mean when I wire it to mains equipment?

Each relay’s contacts are rated to switch resistive loads up to 10 amps at 250 volts AC, with a response time under 20 ms and a mechanical life of 100000 operations.

How does the high-level trigger at 1.3V work with a 3.3V ESP8266 GPIO?

The module triggers on a high-level signal of 1.3V, so a 3.3V GPIO from the ESP8266 drives the optocoupler (EL817) directly without extra level-shifting.
