I am applying 5V DC on VCC and 3V signal without a click on the relays.** A: The relay attached to your question requires 12vdc input to the coil. They are available with 5vdc coil input voltage. Hope this helps. **Q: Is there an on-board way to make both relays work simultaneously, aside from a jumper wire between the two IN ports?** A: Iā€™m not sure I really follow the purpose of your ā€œ Without a Jumper ā€œ . To make both work together they need to be linked OR the device you are triggering from needs to send 2 independent triggers. If the objective is just to avoid a physical jumper then the other option is a solder link on the underside. **Q: can the input handle 9v?** A: Stick a resistor inline ! ## Frequently Bought Together - AEDIKO 4pcs DC 5V Relay Module 2 Channel Relay Board with Optocoupler Support High or Low Level Trigger - AEDIKO 4pcs DC 5V Relay Module - 1 Channel Relay Switch Board with Optocoupler Isolation, High or Low Level Trigger - AEDIKO 2pcs DC 5V Relay Module 4 Channel Relay Board Shield with Optocoupler Isolation Suport High/Low Level Trigger --- ## Why Shop on Desertcart? - šŸ›’ **Trusted by 1.3+ Million Shoppers** ā€” Serving international shoppers since 2016 - šŸŒ **Shop Globally** ā€” Access 737+ million products across 21 categories - šŸ’° **No Hidden Fees** ā€” All customs, duties, and taxes included in the price - šŸ”„ **15-Day Free Returns** ā€” Hassle-free returns (30 days for PRO members) - šŸ”’ **Secure Payments** ā€” Trusted payment options with buyer protection - ā­ **TrustPilot Rated 4.5/5** ā€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/361376111-4pcs-dc-5v-relay-module-2-channel-relay-board-optocoupler](https://www.desertcart.pl/products/361376111-4pcs-dc-5v-relay-module-2-channel-relay-board-optocoupler) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-26*
