When I used one of these the outputs were active. I wired it like data sheet. I tied the output + to my plc analog input and the - to my DC common in my control panel. The other output went straight to a panel meter. I don’t know if it’s possible to wire outputs passive. You might give ASI a call. Sorry I couldn’t be more help. ## Frequently Bought Together - 4-20mA Signal Splitter | 1 Input, 2 Isolated Outputs | 24V DC Powered | High Accuracy | DIN Rail Mount - MEAN WELL EDR-120-24 Single Output DIN Rail Power Supply 24V 5 Amp 120W - ASI ASI451141 4-20mA Analog Signal Splitter, 1 Input, 4 Output --- ## 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.ph/products/16622746-4-20ma-signal-splitter-1-input-2-isolated-outputs-24v](https://www.desertcart.ph/products/16622746-4-20ma-signal-splitter-1-input-2-isolated-outputs-24v) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-08-29*
