The Sundstrand Sauer R7232A1010 Remote Amplifier is a high‑current power module used to drive hydraulic or pneumatic actuators in construction and industrial equipment. Common failure modes for this class include overheating of the MOSFET array, degradation of the gate driver ICs, and insulation breakdown between the output terminals and chassis ground. Initial diagnostics should verify that the supply voltage and current limits are within spec, inspect the PCB for burn marks or cracked solder joints, and check the output stage for excessive temperature or abnormal voltage spikes. If the unit passes these checks, proceed to test the gate driver logic and measure the output resistance under load.[oss-gpt-20b]
