Load was no more than 3 amps. Relay is now stuck. If 12v trigger is removed the relay state doesn't change unless I tap it with a screwdriver handle. I'm now returning it ## Features - Stable Performance --- The Relay Board adopt patch photocoupler isolation, strong driving ability, stable performance. Trigger current is 5mA. The module can be high or low by a jumper setting trigger.The module uses genuine quality relay, normally open interfaces. - Fault-tolerant Design --- This relay board 12v with Fault-tolerant design,even if the control line breaks,the relay will not move. Power indicator light (green), 4-way relay state indicator light (red). - More Choice --- Relay module operating voltage is 5V,12V,24V for choice. Each path of the module can be triggered by the high level or low level through a jumper setting. - Humanized Interface Design --- This 1 Channel Relay Module with Humanized interface design, all interfaces can be directly connected through the terminal lead, very convenient. Four fixing bolt holes are provided. Standard interface that can be controlled directly by microcontroller ( ,, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic) - After-sales Service --- We stand behind all of our them with a product guarantee and promise to give you the best in customer care!

Load was no more than 3 amps. Relay is now stuck. If 12v trigger is removed the relay state doesn't change unless I tap it with a screwdriver handle. I'm now returning it ### ⭐⭐⭐⭐⭐ Really cool device *by M***S on 19 September 2023* I ordered single module to test it as I need at least 3 module device (so already ordered a 4 relay module). I used it to connect a 12v push switches in the work top to control 240v lights on the ceiling coving and under cabinets in the living room. It didn't work at the beginning but I switched the yellow connector on the pin to low voltage I believe, and it started to work. Not sure how long it will last but looks well built. ## Frequently Bought Together - Keenso 1 Channel 5V/12V/24V Relay with Optocoupler, High & Low Level Trigger - Innfeeltech 1pcs DC 12V Relay Module 1 Channel Relay with Optocoupler High or Low Level Trigger Expansion Board - AEDIKO 4pcs Relay Module DC 24V Relay Board 1 Channel with Optocoupler Isolation Support High or Low Level Trigger --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/133755428-keenso-1-channel-5v-12v-24v-relay-with-optocoupler-high](https://www.desertcart.vu/products/133755428-keenso-1-channel-5v-12v-24v-relay-with-optocoupler-high) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-06-05*
