imc CRONOSflex: input modules

As part of the imc CRONOS family, the new imc CRONOSflex continues the tradition for supporting direct measurements of virtually any sensor available for mechanical, electromechanical, and mechatronic measurements. Multi-channel mixed signals, whether analog inputs, counters and incremental encoder inputs, or field bus based signals such as CAN-bus, GM LAN or LIN… you name it: imc CRONOSflex measures it.

Modular measurements
With up to 100kSps per channel, and now supporting up to 2 million samples per second throughput in each base unit, as well as having software configurable high precision signal conditioners and integrated sensor power supplies - the imc CRONOSflex can take on even the toughest data acquisition challenges, while performing at high precision under demanding environmental conditions.

The most striking feature of the imc CRONOSflex system is the imc Click Mechanism - you can add or remove signal-conditioned analog input channels from your imc CRONOSflex system in seconds by simply "clicking" a module on or off the stack. The module's rigid case and automatic recognition by the imc STUDIO software provide the ultimate in flexible modularity. Alternatively, the imc CRONOSflex Modules may be distributed, connected with the base unit or other satellite blocks via standard Ethernet cable.

As with all imc data acquisition system inputs, the imc CRONOSflex Modules integrate signal conditioning, analog filtering, high precision 24-bit digitizers, and digital signal processing. As such, a variety of modules are available from imc—from the general purpose universal 8-channel UNI2-8 module (CRFX/UNI2-8), to more measurement specific modules.
