ISAM (C08ab700)

ISAM (C08ab700)

The 8 channel Intelligent Signal Analyzer Module ISAM from CGS is a multifunctional module with 3 functions:

• PWM analyzer (decoder) with max. 8 channels
• Incremental decoder with max. 12 channels
• Edge counter with max. 8 channels

The 12 channel incremental decoder uses for decoding a state machine integrated in an FPGA to provide reliable values without counting errors. Such miscounting can occur during conventional decoding using I/O modules and software, e.g. by micro-vibrations (multiple directional change before the end of the signal sequence) caused by servomotors.
