## Description

SainSmart 8-Channel Solid State Relay Board is a well-received professional device with a longer life span, faster switching time and are far more tolerant to high induction loads. It has good looking, nice design and excellent performance! You would have wonderful experience using this product!General Product InformationSSR Output (each channel): Load voltage range: 75 to 264VAC (50/60Hz). Load current: 0.1 to 2 AMP.Power supply: 5VDC / 160mA (all channel ON). Input control signal voltage: 0V - 0.5V Low stage (SSR is OFF) 0.5V - 2.5V (unknown state). 2.5V - 20V High state (SSR is ON).SSR Spec.: Part number: G3MB-202P, 5V version. Isolation: Phototriac. Zero cross: Yes. Rated output load: 2A at 100 to 240VAC.(50/60Hz). Load type: General purpose.NOTE Please contact us if you need the Schematic Each Set of Package Contain 1 x SainSmart 8-Channel Solid State Relay BoardOur store M&S affords many different accessories of relay boards, you can freely shop in our store and choose the appropriate products for you!

We work with manufacturer closely and did a lot of enhancements on similar products.

Review: Fantastic bit of kit - This relay board is well built and works well with the Raspberry Pi or Arduino kit. Highly recommended for anyone looking for 8 channel relay control. I have only had this working for a few days but so far so good. (Switching lights) Also remember the relays are good for switching a maximum of 440Watts at 220V. So don't go switching your kettle or microwave as it will burn out! Overall I would definitely buy another one.
Review: Works fantastically, but make sure you get a schematic - You look at a board and assume it works one way... and then you get a loud snap and a cloud of magic smoke. Always read the schematic. Other than that, works brilliantly (I bought a second one after realising my mistake). Well put together bit of kit and at a great price.

### ⭐⭐⭐ Poor description, be cautious
*by A***R on 20 February 2018*

Description of product does not say that it can only switch 75V AC or more. I needed to switch 12V DC and so these were no use. I do not know if the product is a good one or not, I have rated the product low due to the lack of info in the description, this info is not even in `product details` but lower in the extended information.
