1 Data Sheet Version 1.4 AUDIO2-4 for imc CRONOSflex (CRFX/AUDIO2-4) 4-channel Audio Measurement Module The imc CRONOSflex Audio Measurement Module (CRFX/AUDIO2-4) is specially designed for acquisition of sound and vibration data. In addition, acquisition using ICP - or DeltaTron-Sensors. The module can be used for very precise measurements over a wide voltage range. It stands out by a very large signal noise distance and high signal fidelity. In combination with the wide bandwidth and the 24 bit resolution a broad scope of measurement applications is covered. Nearby each signal input at the front of the module there is a LED for a probe breakage recognition in measurement mode/coupling "AC with current feed" Highlights Channel individual galvanically isolation Signal bandwidth 49 khz Supports imc Plug & Measure (TEDS, Transducer Electronic Data Sheets (IEEE 1451) imc CRONOSflex Audio Measurement Module (CRFX/AUDIO2-4) imc CRONOSflex - Frameless expansion, flexible modularity An imc CRONOSflex system is composed of a base unit (CRFX-400 / CRFX-2000G) and one or more modules. These modules are designed to be directly connected to one another. The imc Click Mechanism and extruded aluminum case provide a firm mechanical and electrical connection. As a result, no mainframe or rack is needed. In addition when a module is added it is automatically recognized by the software displaying its dynamically assigned ID on the front of the module. Alternatively, connection can be made by means of standard Ethernet cables (RJ45, CAT5) thus creating a spatially distributed system. imc CRONOSflex Modules can be operated without the base unit when used as components within an EtherCAT-based automation system operating as EtherCAT slaves with full CANopen over EtherCAT (CoE) support. imc Click Mechanism imc CRONOSflex distributed system Overview of the available variants Order Code article number Remarks CRFX/AUDIO Standard CRFX/AUDIO2-4-ET extended environmental range 1
