Modular Architecture as its best. The PQM-100 allows the combination of one CPU module and up to 6 selected input modules into one device. The input modules provide input signal isolation, filtering and A/D conversion. The CPU module is equipped with a FPGA real-time controller for the calculation of all parameters and to provide all interfaces and data storage.
