DATA SHEET labV8x3-Iso II labV8x3-Iso II-V1 labV8x3-Iso II and labV8x3-Iso II-V1 are 24-channel HEADlab input modules designed for triaxial accelerometers, featuring electrical isolation of their channels, which makes them suitable for use in electromagnetically demanding environments. They differ only in the configuration of the eight interfaces (¼–28 UNF or ECG.0B.309.CLN – LEMO). HEAD acoustics GmbH Code 3756_3756-V1, Rev. 01, subject to change, last update: 05/

fabV8x3-Iso II Code 3756 A key advantage of both /abV8x3-lso II and the /abV8x3-Iso II-V1 variant is their extended operating range. The eight triaxial inputs are electrically isolated from one another and from the digital HEAD//nk interfaces, enabling the device to be used even in electromagnetically demanding environments. In addition, both input modules feature flexibly configurable sampling rates of 2.048 kHz up to a maximum of 204.8 kHz. The input modules are connected to a HEAD/ab controller, which— depending on application requirements—can itself be connected to additional controllers,...

Input ChannelsElectrical Isolation labV8x3-Iso II and labV8x3-Iso II-V1 each provide eight triaxial inputs for direct connection of the sensors. The three signal lines of each input share a common ground that is electrically isolated from the grounds of the other inputs as well as from both HEADlink interfaces. This enables triaxial accelerometers to be used without case isolation, even in electromagnetically demanding environments. Both input modules use HEADlink 2.0 for data transfer to the controller. In this way, a maximum sampling rate of up to 204.8 kHz is achieved. Furthermore, they are...

Control (ArtemiS SUITE) For configuration and control purposes, labV8x3-Iso II and labV8x3-Iso II-V1 are connected to a controller, which is subsequently connected to a computer via USB or LAN. The computer must have ArtemiS SUITE installed, and licenses for APR Framework (APR 000) and for either the Recorder or Impact Measurement must be available. Recorder (APR 040) The Recorder features a task-oriented and clearly arranged user interface that is very easy to operate and suitable for a wide range of measurement scenarios, from simple start/stop recordings to complex, sequence-controlled measurement...

1 Valid for: ambient temperature 23 °C, 73.4 °F (±3 °C, ±5.4 °F ), operating duration >1 h. Vibration excitation of the device may cause deviations. All measurement ranges are calibrated at the factory. In addition, the measurement ranges 0.1 Vp to 10 Vp can be calibrated in our accredited calibration laboratory in accordance with DIN EN ISO 17025. There is no standardized method for calculating the "dynamic range". Therefore, the signal-to-noise ratio (SNR or S/N) has been specified for /abV8x3-Iso II and /abV8x3-Iso II-V1. It is calculated as the ratio of the level of a full-scale sinusoidal...
