MOOG T161-902A-00-B4 High Precision Electro-Hydraulic Servo Control Amplifier Board

MOOG T161-902A-00-B4 is a rack-mounted analog servo drive board for MOOG high-response electro-hydraulic servo valves. It converts 0–±10V analog command signals into 

high-current driving output to control spool displacement, with built-in closed-loop position feedback compensation circuit to eliminate hydraulic non-linearity, oil temperature and 

pressure interference. Widely used in flight simulators, material testing machines, precision hydraulic presses and aerospace test benches, it is a core spare part for hydraulic motion 

control system overhaul and fault replacement.
