Vibration control and data acquisition system

Top-of-the-line vibration control system for electrodynamic shakers, featuring up to 8 input channels in one box, direct control of power amplifiers, support for voltage and temperature measurements, and combined vibration and climatic tests.

A direct successor to RL-C21, RL-C21M is an advanced multi-purpose device with improved metrological characteristics and powerful testing capabilities:

  • Extended frequency range: DC ÷ 80000 Hz;
  • Extended voltage measurement range up to 40 V;
  • DC current and DC voltage measurement;
  • Thermistor and thermocouple connection.

The device has a modular scalable architecture and comes in two modifications with up to 8 input channels in one unit. RL-C21M can be scaled up to 64 input and 16 output channels to perform multishaker vibration testing or acquire data from a large number of sensors.

RL-C21M system allows for direct power amplifier control and combined vibration and climatic tests. The controller visualizes temperature and humidity-related data and generates automatic reports.

RL-C21M combines three primary functions in one box thanks to the dedicated software solutions:

  • Vibration testing system with a vibration control software TestUP
  • Sensor calibration system with a calibration module
  • Data acquisition system with software for data recording and analysis SignalUp
