There’s an opto-coupler in the circuit with the transmit side connected to the 24vac inputs. Going the opposite direction is theoretically possible but would require a different board **Q: Anyone know a way to crisp the output for higher frequency? at ~4kHz there's a fairly significant rise/drop time that's increasing Vrms about 20~30%** A: You would need to reduce the resistance of the output "pullup" resistor. You could do this by soldering a lower value resistor in parallel with the output pullup resistor. This would be challenging for the average person to do since the pullup resistor is a very small surface mount chip. **Q: Any way to get the common anode configuration (where high in is high out) without sharing the anodes? i don't want in to share power or ground.** A: If you connect your source voltage to the 1+ input and connect your input signal to 1- then the output signal O1 will be "high" (VCC) when your input signal is high. But if you connect your input signal to 1+ and your input side GND to 1- then the output signal O1 will be "low" when your input signal on 1+ is high. **Q: What exactly does this do for me? What kind of signal will it boost??** A: It isolates the input circuit from the output circuit and changes voltage levels from input to output. Depending on how you connect to the input ,it can function as an inverter or a simple buffer with voltage translation. ## Frequently Bought Together - 5 PCS Optocoupler Isolation Board, Icstation DC 12V Optocoupler Isolation Module EL817 1 Channel Opto PNP NPN Signal Converter, Isolator High-Level Trigger 80KHz - AEDIKO 4pcs DC 5V Relay Module - 1 Channel Relay Switch Board with Optocoupler Isolation, High or Low Level Trigger - NOYITO 1-Channel PC817 Optocoupler Isolation Module Optoelectronic Isolator Signal Isolation and Anti-Interference 3-5V 12V 24V (Pack of 2) (3-5V) --- ## 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.bo/products/41227377-5-pcs-optocoupler-isolation-board-icstation-dc-12v-optocoupler-isolation](https://www.desertcart.bo/products/41227377-5-pcs-optocoupler-isolation-board-icstation-dc-12v-optocoupler-isolation) --- *Product available on Desertcart Bolivia* *Store origin: BO* *Last updated: 2026-09-06*
