KB Signal Isolator, Model KBSI-240D

The KBSI-240D is an industrial signal isolator made by KB Electronics. It’s used to isolate and condition analog signals (voltage or current) from controllers, transducers, PLCs, etc., before sending them into motor speed controls or other automation equipment. It accepts various DC input ranges and outputs a linear isolated DC signal (up to 10 VDC) for control systems, helping reduce noise and ground-loop issues. kb-controls.com 📌 Key functions: Isolates non-isolated signals Accepts voltage or current inputs Works with a wide range of signal inputs (e.g., 0-25 V, 4-20 mA) Operates off 115 V or 230 V AC supply Adjustable MIN and MAX trimpots for scaling signals
