The SHOWA SOKKI MODEL-9403 is a Combined Simple and Precision Diagnostic Amplifier for PLC, designed for continuous vibration measurement (acceleration, velocity, displacement) with three selectable ranges. It provides AC output for precision diagnostics (FFT) and DC output for simple diagnostics, delivering real-time vibration data to PLCs. Featuring DC 24V power and DIN rail compatibility, this amplifier is ideal for detecting machine abnormalities in machining tools, gearboxes, motors, and bearings, facilitating early degradation detection and factory automation.
