Vibration Controller RL-C21M

This Vibration Control System is for electrodynamic shakers.  It provides vibration control and data acquisition system for the shaker in one unit.

Featuring 8 input channels, direct control of power amplifiers and climatic chambers.  As well as support for voltage and temperature measurements.

The Rula-Tech RL-C21M is a Vibration controller and the next model up from RL-C21.  Firstly, this product has adaptable architecture.  The 8 input channels can be scaled up to 64 channel inputs and 16 channel outputs.

Secondly, this system allows for direct power amplifier control and combined climate and vibration tests. The controller records and visualises temperature related data automatically.

Use the vibration software packages VISProbe SL & VisAnalyser for all your analysis.


Features of the Vibration Controller RL-C21M include:

  • Extended Frequency Range DC / 80,000 Hz
  • Extended Voltage measurement range up to 40 V
  • DC current and voltage measurement
  • Thermistor and Thermocouple Connection
