Rl-C21M

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

Frequently Asked Questions (FAQ)

TestUP does not see the device. There is a message saying that the device has not been found.

Check the connection of Ethernet cable to the device and PC. Check if the device is loading. The words “RL-C21” should appear on the screen, and if you hold the “Stop” button for more than 3 seconds, it will display the information about the IP-address, serial number and the subnet mask. Another thing to check in case TestUp does not see the device is whether Windows Firewall is enabled and whether there is an antivirus installed. They should be disabled.

Are the settings of channels and shakers, which I specify, saved?

The settings are saved to separate databases, and, having specified them once, you are able to use those in all tests.

Can any problems occur due to the antivirus installed on my PC?

We do not recommend using anti-virus programmes on your PC when working with RL-C21. As the PC communicates with the devices through the network, the antivirus software may sometimes block the data transfer. In case the antivirus software is installed and cannot be deleted, we recommend adding TestUp and the folder, to which it is installed, to the list of antivirus exceptions, or disable the protection.

There is high noise level on the shaker, caused by the product, which is operating on it outside the testing zone. How do I not take it into consideration during control?

If it is Sine test, you should set the “Synchronous detector” control algorithm for the control channel. In case of Random test, select the “in the task spectrum” parameter in the drop-down menu “RMS is calculated in…” of the “Control” tab.
