Moog G123-817-006 LVDT Oscillator Demodulator Module

Product Description

The Moog G123-817-006 is a general-purpose LVDT oscillator and demodulator board, upgraded version of G123-817-002. It is designed for series opposed 4-wire LVDT displacement sensors, widely used in Moog servo hydraulic control systems. It features improved common-mode noise rejection, stable excitation output and high-precision signal demodulation. This legacy Moog electronic module is stocked as spare parts for steel mill, test bench and hydraulic servo system maintenance and retrofit.

Product Functions

• Generate adjustable excitation oscillator signal for 4-wire opposed LVDT sensors
• Demodulate AC feedback signal from LVDT and convert to standard DC output signal
• Support adjustment of oscillator level, frequency, phase, zero point and span
• Enhanced common-mode noise suppression for strong electromagnetic interference environments
• Provide accurate displacement feedback signal for servo valve closed-loop control
• Conformal coating and compact PCB design for installation inside servo control cabinets

Application Scenarios

• Moog servo valve and hydraulic closed-loop motion control systems
• Steel rolling mill, hydraulic press and material test bench equipment
• Aerospace and automotive multi-axis simulation test rigs
• Power plant turbine hydraulic actuator position monitoring
• Spare replacement and repair of existing Moog LVDT feedback control units
