Vibration Amplifier Model-9403 ｜ Dual DC/AC Output for PLC Monitoring & FFT Analysis

Showa Sokki Model-9403 vibration amplifier with dual DC/AC outputs, PLC integration, and FFT analysis capability.
🔷 Model-9403 – Dual-Function Vibration Amplifier for PLC and Diagnostics
The Model-9403 from Showa Sokki is a multi-purpose vibration amplifier designed to support both basic monitoring (DC output) and detailed waveform analysis (AC output) from vibration sensors.
It features three selectable measurement modes—Acceleration, Velocity, and Displacement—easily switched via internal jumpers. Users can also select output levels (LOW / MID / HIGH) to match specific applications.
With its DC True RMS output, the 9403 can be directly connected to PLCs for continuous monitoring, while its AC raw waveform output makes it ideal for detailed diagnostics using FFT analyzers. The Through-Out function enables sharing of a single sensor signal across multiple devices, reducing system complexity.
🔷 Key Features
