20 Industrial Data Acquisition and Control System encompasses more than 25 years of design excellence and quality in the industrial test and measurement and control industry. This powerful, high performance, highly flexible system offers the industry's lowest cost per channel, integral PID loop control, and ±0.035% system accuracy (module dependent). It is ideal for test and measurement, factory and process automation, machine automation, military and aerospace, power and energy, environmental monitoring, and oil and gas applications.
The MAQ20 family consists of DIN rail mounted, programmable, multi-channel, industrially rugged signal conditioning input and output modules and communications modules (Figure 1). Each I/O module has a 1500Vrms isolation barrier between field-side and system-side wiring, and many models offer per-channel isolation. All field wiring terminals are heavily protected against overload, accidental connection of incorrect signals, and ESD. Modules mount on the industry standard 35x7.5mm gull-wing DIN rail. A backbone mounts within the rail providing power and communication interconnections between the communications modules and each I/O module.

Can MAQ20-BRDG1 support a strain sensor such as a load cell, can it measure stress?
MAQ20-BRDG1 can measure any millivolt signal as long as it is within the limits specified for input voltage defined by sensitivity multiplied by excitation voltage and within the bandwidth. Where strain, load, weight, stress, etc. need to be measured, that is in part dependent on the sensor and how it converts those parameters into millivolts and in part on scaling in software.
Keywords/Phrases: MAQ20-BRDG1, strain, strain gage, strain gauge, load cell
Is it possible to provide external power supply directly to the backplane rail instead through the MAQ20-COM2 front panel?
The MAQ20-COMx module has to be powered through its power connector and it powers the backbone to power the I/O modules.
If you powered the backbone too, then that power supply would fight the power supply from the COM module and they would likely damage each other.
How do I convert an RMS voltage to its corresponding peak voltage?
To convert an RMS voltage to its corresponding peak voltage, you simply take the RMS voltage value and multiply it by the square root of 2, or roughly 1.414.
For example, 1500Vrms corresponds to a peak voltage of 1500 * 1.414 = 2121 Vp
How do I register / unregister modules in a MAQ20 system?
The media attachment "MAQ20ModuleRegistrationStrategies.pdf" in the "Media Attachments" box to the right is an excerpt from the MAQ20 Communications Module HW User Manual.pdf.
This attachment describes in three sections the standard and alternate setup processes involved in Building a System, Section 7.0, Maintaining a System, Section 8.0, and Expanding a System, Section 9.0.
In addition, MAQ20 I/O Module Registration, Section 10.0, provides a functional description of the automated registration process and information about tools enabling user reassignment of Registration Numbers. Calculated examples of: a write to the Module Detect Register at I/O module address 98 plus the module offset based on Registration Number will trigger a module to visually self-identify by blinking the STAT LED and how to calculate the base address for reading 16 channels of Current Data for a MAQ20-VSN module.
Does USB have a faster response time than Ethernet when communicating with the MAQ20?
The MAQ20 ideally has equally fast response times regardless of whether you use USB or Ethernet connection. Other variables outside of the MAQ20 can influence this response time however, such as if you are using a USB to Ethernet adapter or if the MAQ20 is part of a larger company network.
Can I copy and paste data from ReDAQ Shape while in acquisition?
Yes, ReDAQ Shape has the ability to directly copy and paste raw data from the "Analyze" tab, without interrupting the acquisition process. However, you must use the "Copy To Clipboard" button located at the top left corner of the raw data table - using keyboard commands or right clicking and selecting "Copy" will not work.
Can I export data from ReDAQ shape to a text file or Excel spreadsheet?
Yes, ReDAQ Shape offers the option to export data to a .txt file or Excel spreadsheet live without interrupting the data acquisition process. Simply click the "Open Data File" or "Open Excel File" button in the "Analyze" panel.
Can I still export my acquired data to a text file or Excel spreadsheet with the User version of ReDAQ Shape?
Yes, these options are available in both the User and Developer versions of ReDAQ Shape.
How does the load resistance of a module affect the noise at the output?
Noise at the output of a module is independent of load resistance.
How are unlock keys used to license IPEmotion?
Unlock keys are generated from the serial number of the COM module of the system that you purchased. These unlock codes are also generated based on how many I/O modules are in the MAQ20 system. You won't be able to run the data acquisition process in IPEmotion unless you have entered the correct unlock code for your system and the I/O module count of your system is equal to or below the allotted I/O module count determined when the unlock code was generated.
For example, if you purchased an unlock key for a MAQ20-COM2 with 1 MAQ20-VO, 1 MAQ20-VDN, and 2 MAQ20-BRDG modules, this would correspond to an I/O module count of 4. If you attempted to run the acquisition process with this configuration, it would work perfectly. If you decided to remove the two MAQ20-BRDG modules, you would still be able to run the acquisition process. However, if you were to add a MAQ20-FREQ module to your system, bringing your total I/O module count to 5, IPEmotion will not let you start the data acquisition process until the I/O module count is back to 4 or lower.
If you have more than one MAQ20-COM module in your system, it is not necessary to enter additional unlock codes for the extra COM modules.
How are unlock codes used with ReDAQ Shape?
Unlock codes are generated based on the serial number of the COM module of the system you purchased. If you are running an unlicensed version of ReDAQ Shape you sill have access to all the features of the software, but are limited to 1 hour of usage until the software stops. Entering the unlock code associated with your MAQ20 system will remove the time limit and allow unlimited usage of ReDAQ Shape. You must purchase an unlock code for every COM module you are using in order to have unlimited usage of ReDAQ Shape.
Note: Licenses purchased for the Developer version of ReDAQ Shape are not compatible with the User version, and vice versa.
Does the MAQ20 support tachometer input?
Yes, the MAQ20-FREQ module can support tachometer input. Please reference the user manual for the MAQ20-FREQ module for more information on how to process RPMs.
Where do I download the USB drivers for the MAQ20 to be used with ReDAQ Shape?
There are two places that you can download the USB drivers for MAQ20. If you haven't already downloaded ReDAQ Shape, you will be given the option to download the required USB drivers during the installation process. If you already have ReDAQ Shape downloaded and you somehow lost the USB drivers, you can download them from our website. The USB drivers for the 8B isoLynx SLX300 system are identical with the USB drivers for the MAQ20.
