RL-C21M: Vibration Control and Data Acquisition System
RL-C21M: Vibration Control and Data Acquisition System
Top of the line vibration control system RL C21M for electrodynamic shakers, featuring up to 8 input channels in one box, direct control of power amplifiers and climatic chambers, as well as support for voltage and temperature sensors.
RL C21M has a modular scalable architecture and constructively comes in two modifications with up to 8 input channels in one unit. It can be scaled up to 64 input and 16 output channels.
The system provides direct power amplifier control and combined vibration and climatic tests. The controller records and visualizes temperature related data automatically. RL C21M is used with a specialized vibration test software package TestUP.
RL-C21M is an advanced multi-purpose device with improved metrological characteristics and powerful testing capabilities:
Frequency range: DC ÷ 5 kHz;
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 acquire data from a large number of sensors.
RL-C21M system allows for direct power amplifier control and climatic tests. The controller visualizes temperature and humidity-related data and generates automatic reports.
RL-C21M combines two primary functions in one box thanks to the dedicated software solutions:
Sensor calibration system with a calibration module
Data acquisition system with software for data recording and analysis SignalUp

Technical FAQ
Where can I get a software update?
On our website in the Downloads section. Please mind that you need to log in to download the updates. You can access the demo software version without logging in.
During start-up the signal from the sensor is “too great/small”.
First of all, check the correctness of the sensor type settings (ICP, charge or linear) in TestUp software, and the sensor sensitivity. If the problem is still there – no signal, or it is too small, check the integrity of the sensor cable. If the problem has not been solved, check the ICP power current (in case it is an ICP sensor) or connect the sensor to a different channel.
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.
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.
