The Sundstrand Sauer T7232A1010 Remote Amplifier is a high‑power signal conditioning module used to drive hydraulic or pneumatic actuators in industrial control systems. Common failure modes for this class of remote amplifiers include power supply degradation, overheating of the output stage, and failure of the internal MOSFETs or driver ICs due to voltage spikes or overcurrent conditions. First‑check diagnostics should verify that the input voltage is within spec and that the amplifier’s protection diodes are intact; inspect for burn marks or loose connections on the PCB, and review any fault codes logged in the host controller. If the unit continues to fail after these checks, perform a continuity test of the output transistors and replace any damaged components.[oss-gpt-20b]
