Alinan 4pcs 2 Channel 5V Relay Module with Optocoupler Isolation Low-Level Trigger Development Board Compatible with Arduino R3 MEGA 2560 1280 DSP ARM PIC AVR STM32 Raspberry Pi
Description
Power Supply: 5V; Load Voltage: AC250V 10A,DC30V 10A Perfect used for domestic appliance, office machine, audio, equipment, automobile, etc. (Remote control TV receiver, monitor display, Audio,Raspberry Pi equipment high rushing current use application) Durable Material: Selection of plastic material for high temperatures and better performance of chemical solutions Size: 1.97 inches x 1.54 inches x 0.63 inches/50.5mmx 38.5mmx 18.5mm Package Included:45v 2-channel relay module
Features:
- Standard interface that can be controlled directly by microcontroller (compatible with Arduino ,Raspberry Pi, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic).
- There is an isolation slot between the control area and the load area; genuine relays are used; there are power supply and relay action indications, which are on when they are on and off when they are disconnected; when there is a signal at the signal input end, the common end and the normally open end will be connected; it can be used as a microcontroller for development Board module, can be used as home appliance control.
- Control DC or AC signal, can control 220V AC load; there is a normally open and a normally closed contact; the blue KF301 terminal is more convenient to connect the control line.
- High-level triggering refers to a triggering method in which there is a voltage between the signal input terminal and the ground, which can be understood as a short-circuit triggering method between the signal input terminal and the positive pole of VCC.
- Low-level triggering refers to the triggering method in which the voltage between the signal input terminal and the ground is OV, which can be understood as a method of short-circuit triggering between the signal input terminal and the negative pole of GND.
