Stand-alone Ethernet DAQ system released

0

ADLINK Technology, manufacturer of advanced edge computing products, has announced the release of its new MCM-204 edge Data Acquisition Systems (DAQ) for machine condition monitoring (MCM).  

Powered by the ARM Cortex-A9 processor, the MCM-204 is designed as a standalone DAQ device without the need for a host computer, and provides dual Ethernet ports to transmit data back to the backend server and enable daisy-chain connection of multiple devices.  

Commonly used vibration-related indices, such as voltage, FFT, and RMS, can be calculated additionally the MCM-204 offers flexible support for various data access options, providing remote management and firmware/algorithm update through the built-in web console.   

“Conventionally, in order to provide constant machine monitoring, a DAQ system consisting of an embedded host computer and DAQ card are deployed at remote machine sites. However, when remote machines are numerous and spread out geographically, the deployment of DAQ systems at each site becomes prohibitive,” said Tim Juan, director of ADLINK’s IoT solutions and technology. 

“The MCM-204 standalone edge system can be easily integrated at field sites, and perform the task of filtering raw data without the need for a host computer, significantly reducing the required data bandwidth, and ultimately allowing manufacturers and machinery suppliers reduce TCO by up to 70% and improve their ROI.” 

The MCM-204 also features a 24-bit high resolution ADC and captures high-frequency signals at 128kS/s. All channels have a built-in IEPE 4mA excitation current source, eliminating the need for additional signal conditioning to trigger sensors to capture signals. In addition, the MCM-204 can also support digital tachometer, digital temperature sensor, and voltage output load current sensor functions for acquiring rotating speed, temperature and load current of the machine. Furthermore, the unit has rich built-in data type support, including as voltage, FFT data, and RMS_OA.  

To enable a decentralized structure, the ADLINK MCM-204 offers an exclusive Custom Filtering Algorithm import mechanism that allows users to modify filter or pre-processing algorithms in C/C++ and compile under Linux. The MCM-204 provides the ability to migrate domain-knowhow filtering algorithms to the edge in a secure manner.
