Product Highlights
- A solid state relay is similar to 1 channel 5v relay module solid state high-level ssr dc control 250v 2a with resistive to a mechanic relay where it can be controlled through a digital signal. solid state relay generates no noise and has a much longer lifespan compared to the traditional mechanic relay.
- Use it to control various appliances and other equipment with a large current.
- This is a 1 channel 5v solid state relay module. a solid-state relay (ssr) is just what it sounds like; an ic that acts like a mechanical relay. they allow you to control high-voltage ac loads from lower voltage dc control circuitry. they accomplish this by using infrared light as the contact, a solid-state relay is really just an ir led and a photo triac sealed up into...
- When the input logic voltage is applied to the coil, the nc will disconnect from the com breaking the conductivity between the two. at the same time, the no will connect with the com allowing conductivity between them. depending on your wiring this will turn on or off the connected load.

Product Highlights
- This level converter works with 2.8v and 1.8v devices, it can bidirectionally transfer with 4 channels between high logic voltage and low logic voltage.
- The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. high voltage (5v for example) to the ‘hv’ pin, low voltage (3.3v for example) to ‘lv’, and ground from the system to the ‘gnd’ pin.
- The bi-directional logic level converter is a small device, which can safely steps down 5v signals to 3.3v and steps up 3.3v to 5v at the same time.
- Each logic level converter has the capability of converting 4 pins on the high side to 4 pins on the low side with two inputs and two outputs provided for each side.
- Package include: 2 piece iic i2c logic level converter bi-directional module
