ICPU2-8 for imc CRONOSflex (CRFX/ICPU2-8)

Transcription

1 Data Sheet Version channel IEPE/ICP-Measurement Module The imc CRONOSflex IEPE/ICP Measurement Module (CRFX/ICPU2-8) is ideal for the use in sound and vibration measurement engineering. Highlights Direct connection of IEPE/ICP-sensors via BNC inputs High signal bandwidth of up to 48 khz per channel Wide input-voltage range of 5 mv to 50 V, individually software selectable per channel Input coupling switchable via software: DC, AC, AC with current supply Supports imc Plug & Measure Transducer Electronic Data Sheets (IEEE ) Typical applications: Noise and vibration analysis General measurement of dynamic acceleration imc CRONOSflex IEPE/ICP Measurement Module (CRFX/ICPU2-8) 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 CRFX/ICPU CRFX/ICPU2-8-ET remarks standard extended environmental range Terminal connections Measurement inputs: System bus (EtherCAT): 8x BNC 2x network plugs RJ45 1
