Once I replaced the mechanical relays with these relays, the Arduino sketch ran great. I needed to control 7 amps with a 12 mp surge, but I ordered the 40amp relay, just in case. It's 5 months later and they still work. Review: SSDs at their best. - These Solid-State relays were exactly what I was looking for. If you need some, these are as good as you will find. I highly recommend them. When I needed some, many years ago-they were like $25 apiece. Now a days they are much more reasonable. Buy them. ## Features - 【Model】SSR-40DA 40A 250V Solid State Relay Module, for PID thermostat temperature controller - 【SSR-40DA Parameter】Solid state module relay SSR-40DA, 3-32VDC/24-380VAC, control mode: DC to AC - 【Relay Size】(L*W*H)62×45×24mm/2.48 x 1.73 x 0.94" - 【SSR Application】No electric spark, no noise, high switching speed, especially suitable for corrosion, moisture, dust resistant and other harsh environments.
