Description of the product: Grove - 4-channel solid state relay
Module from the Grove series with 4-channel relay SSR with control voltage of 5 V and rated voltage of contacts of 240 V AC and 2 A. Due to the application of semiconductor technology, the relay has no mechanical contacts which positively affects the service life of the equipment. The lack of contacts means no noise during switching.
Grove - 4-channel solid state relay.
Relay from Grove is based onhigh quality G3MC202P module that allows you to use5 V DC to control ofmax. 240 V AC. The module hasfourchannels that can be controlled separately. Thanks to the Grove interface, themodule can be operated in a simple and easy way using Arduino.
The product is compatible with Arduino and Raspberry Pi
Manufacturer has prepared a user manual along with a model program
for Arduino and Raspberry Pi.
Features and application of 4-channel solid state relay from Grove
The advantages to mechanical relay:
- Completely silent operation.
- The lack of physical contact which means no sparks.
- Extended lifespan.
- Compact and thin-walled design SSR.
Disadvantages in relation to the mechanical relay:
- After closing, there is the higher resistance (heat generation).
- Increased electrical noise.
- Works only for AC loads.
The use of solid state relays:
- During operations that require switching with the low delay, for example, a phased inspection of light
- Devices that require high stability, such as medical devices.
- Situations requiring protection from explosion, stain, resistant to moisture, such as coal industry, chemical industry.
