(+12 as in the positive side of the power source) If you set to low, it will trip when their is -12v (technically 0 volts) on INT 1 or INT2 (-12 as in the negative side of the power source) **Q: These are locking in the triggered position (Red light on), even with no trigger voltage. Any ideas, did I get bad ones?** A: When you say no trigger voltage, do you mean that no wires connected? If so then you may have gotten a bad set. Otherwise, check the jumper pins next to the trigger input. See if it set to low. **Q: What is the minimum to maximum voltage for both the low and high?** A: Minimum voltage that will trigger high: 2.5V Maximum voltage that will trigger low: (Vsupply- 2.5V) Measured this with Vsupply values of 12.2V and 13.6V. Used UNI-T UT61E multimeter for voltage measurements. **Q: are these latching relays?** A: No. They have normally open and normally closed contact points and will flip to the normally closed position when the trigger stops. ## Frequently Bought Together - HiLetgo 2pcs DC 12V 2 Channel Relay Module with Isolated Optocoupler High and Low Level H/L Level Trigger Module Triggered by DC 12V - AEDIKO 4pcs DC 12V Relay Module 1 Channel Relay Board with Optocoupler Isolation Support High or Low Level - HiLetgo 12V 4 Channel Relay Module with OPTO-Isolated Support High and Low Level Trigger --- ## 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.co.th/products/7893757-hiletgo-2pcs-dc-12v-2-channel-relay-module-with-isolated](https://www.desertcart.co.th/products/7893757-hiletgo-2pcs-dc-12v-2-channel-relay-module-with-isolated) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-23*
