Review: Works well, the heatsink helps a lot. - This works really well, the heat sink really helps keep it cool. I tried another and it overheated. I use it to switch on a 1.5 HP 16 A dust collector in the shop and I have had no problems with it. I have had this over 3 years. The LED inside to not that it is on, is a little dim compared with the other one I have. Review: Do you need ssr-Da, or do you need a ssr-AA? - Performed so well, I've ordered 2 set's over the last 8 months. Couldn't imagine using anything else. Definitely worth the money! One big call out is. You may want to research the difference between a ssr-Da and a ssr-AA and finally a low voltage contactor for your application needs. I only say this because it appears from the reviews, that many people are miss matching their ssr to their applications. I know that I did this in the beginning and toasted a few myself... Do the research first, it'll pay off in the long run. ## Features - 40A Solid State Relay Specifications:Load Voltage: 24-380VAC - Load Current: 40A - Input Voltage: DC 3-32V - Heat Sink Mounting Thread Diameter (Approx.) : 0.5 cm / 0.19 - Heat Sink Total Size (Approx.) : 8 x 4.9 x 4.9 cm / 3.1" x 1.9" x 1.9" (L * W * T ) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01MCWO35P | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #42,362 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #9 in Solid State Relays | | Color | Black Heat Sink | | Customer Reviews | 4.5 4.5 out of 5 stars (355) | | Date First Available | October 21, 2016 | | Is Discontinued By Manufacturer | No | | Item Weight | 6.4 ounces | | Item model number | ITC-100-LW | | Manufacturer | Lerway Tech | | Material | Aluminum | | Measurement System | Metric | | Package Dimensions | 5.51 x 2.56 x 2.44 inches | | Part Number | ITC-100-LW | | Size | SSR-40DA+Black Heat Sink | ## Images ![Inkbird Solid State Relay 40DA DC SSR Black Heat Sink for PID Thermostat Temperature Controller - Image 1](https://m.media-amazon.com/images/I/71fZ3LQAV3L.jpg) ![Inkbird Solid State Relay 40DA DC SSR Black Heat Sink for PID Thermostat Temperature Controller - Image 2](https://m.media-amazon.com/images/I/61tn+Kzh7wL.jpg) ![Inkbird Solid State Relay 40DA DC SSR Black Heat Sink for PID Thermostat Temperature Controller - Image 3](https://m.media-amazon.com/images/I/61duwk7MCIL.jpg) ![Inkbird Solid State Relay 40DA DC SSR Black Heat Sink for PID Thermostat Temperature Controller - Image 4](https://m.media-amazon.com/images/I/61a9j8toI1L.jpg) ![Inkbird Solid State Relay 40DA DC SSR Black Heat Sink for PID Thermostat Temperature Controller - Image 5](https://m.media-amazon.com/images/I/61sAOvxmvJL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well, the heatsink helps a lot. *by M***B on February 11, 2026* This works really well, the heat sink really helps keep it cool. I tried another and it overheated. I use it to switch on a 1.5 HP 16 A dust collector in the shop and I have had no problems with it. I have had this over 3 years.

Couldn't imagine using anything else. Definitely worth the money! One big call out is. You may want to research the difference between a ssr-Da and a ssr-AA and finally a low voltage contactor for your application needs.

Do the research first, it'll pay off in the long run. ### ⭐⭐⭐⭐⭐ Worked for Creality CR10 S5 AC heated bed *by B***T on July 20, 2021* I mounted this on the upper side of my CR10 S5's PSU for my upgraded bed heater. I upgraded the fans in the control box and added a stand that has a raspberry pi and 12v Noctua fan powered by the Pi's USB. The exhaust from the case is never warm and I never notice a spike in my Pi's temps in octoprint. I was weary of fakes, which seem to be everywhere, but this one has worked great for me. ## Frequently Bought Together - Inkbird Solid State Relay 40DA DC SSR Black Heat Sink for PID Thermostat Temperature Controller - Inkbird PID Temperature Controller Kit, High Voltage 100ACV to 240ACV, Comes with SSR 40DA Solid State Relay, K Type Thermocouple, and White Heat Sink - DaierTek 30A 250V KCD2 KCD4 Rocker Switch DPST 4 Pin Red Lighted 120V Rocker Toggle Switch ON Off Heavy Duty T125-3Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pe/products/35971360-inkbird-solid-state-relay-40da-dc-ssr-black-heat-sink](https://www.desertcart.pe/products/35971360-inkbird-solid-state-relay-40da-dc-ssr-black-heat-sink) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-05-12*
