Product Overview

VT11023‑16A is analog DIN‑rail‑mount servo‑valve amplifier. It converts ±10 V control command signal into proportional drive current for electro‑hydraulic servo‑valve coils. Offset, gain and dither parameters can be adjusted via potentiometers for hydraulic‑loop tuning. Widely used in test‑stands and heavy‑industry hydraulic motion‑control systems. Surplus and refurbished tested spare servo‑valve amplifier module.

Application Notes

‑ Perform offset‑gain tuning after installation and valve replacement. ‑ Use shielded cable for command‑signal and valve‑coil wiring. ‑ Typical deployment: Electro‑hydraulic servo‑valve analog amplifier spare‑part stocking.
