Controllers

Two controllers are designed for the Alemnis Standard Assembly (ASA)

ENHANCED CONTROLLER (ECO)

Real time controller based on FPGA technology for high performance control loop (up to 5kHz frequency for the indenter with or without the VHSRM, and 500kHz with an optional UHS module):

Very high performance multifunction I/O boards (up to 1M samples/s for load measurement with the VHS and the UHS);
-30V to + 150V piezo amplifier for driving the indentation head;
Driver for micro-positioning system.

Optional I/O for HTM, UHS and Auxiliary (4 inputs +/- 10 VDC, 2 inputs for strain gauges and 2 outputs +/- 10 VDC

STANDARD CONTROLLER (SCO)

Multifunction I/O boards for load and displacement measurements (50k Samples/s) and indentation control (100k samples/s);
-30V to + 150V piezo amplifier for driving the indentation head;
Driver for micro-positioning system.
Controller hosted in laptop computer (200Hz frequency):
Optional I/O for high temperature modules
