MEN Micro presented M-Module M36N, an input board for high-speed, resolution and precision requirements in automation, measuring and simulation applications.
The M-Module is used in CompactPCI, peripheral component interconnect (PCI), PCI extensions for instrumentation (PXI) or virtual machine environment (VME) systems as well as in embedded single-board computers.
Especially in the area of industrial input/output (I/O), M-Modules have provided manifold functions for process data acquisition, motion and robotics or instrumentation.
In order to comply with the restriction of the use of certain hazardous substances (RoHS) directive, all M-Modules have either been adapted or redesigned and equipped with new features.
The analog input module M36N provides 16 single-pole grounded channels for voltage or current or alternatively eight channels for differential voltage or current. Each channel and each input range is adjusted separately and automatically.
The resolution is 16 b with an accuracy of at least 0.05% over the whole temperature range from -40 degrees Celsius to +85 degrees Celsius. An analog to digital converter (ADC) and automatic incrementation of the multiplexer channel enable a total acquisition time of 130 µs for 16 b.
The Cyclone II field-programmable gate array (FPGA) implemented on the M36N controls the signal conditioning and offers space for application-specific function extensions of the assembly. The Altera Nios II Softcore processor can be implemented into the FPGA for intelligent pre-data-processing or additional functions such as noise shaping. To do this, it is possible to assemble up to 32 MB double-data-rate 2 dynamic random access memory (DDR2 DRAM) as well as up to 6 MB nonvolatile memory.
The separate supply voltages can be generated via a direct current to direct current (DC/DC) converter on the board, which is also suited for -40 degrees Celsius up to +85 degrees Celsius.
