Product Overview

G123‑825‑001 is DIN‑rail buffer amplifier designed for electro‑hydraulic servo valve signal matching. It converts standard PLC analog output signals into drive signals required by MOOG servo valves. It also supports upgrading old MFB mechanical‑feedback valves to modern EFB electrical‑feedback valves without changing original servo amplifier. Widely used in steel‑mill, test‑stand and hydraulic motion‑control systems电子工程世…. Surplus and refurbished tested spare signal buffer amplifier.

Application Notes

‑ Set DIP‑switch according to valve drive requirement before commissioning. ‑ Use shielded cable for signal wiring. ‑ Typical deployment: Servo valve signal matching buffer amplifier spare‑part stocking.
