The SCES-VSD27-C is a 27-channel voltage/ICP® conditioning unit for semi-differential voltage signals and piezoelectric ICP® sensors. It is designed for measurement applications requiring high channel density and is particularly well-suited for vibration, acoustics, structural, test bench, and multichannel sensor measurements.

The unit provides 27 semi-differential input channels via CAMAC connectors. Alternatively, it can be used in a configuration with 9 triaxial inputs. Supported devices include piezoelectric ICP® sensors, semi-differential voltage inputs up to ±10 V, and sensors with external power supplies.

Compared to the SCES-V27-C, the SCES-VSD27-C is designed for semi-differential inputs. This allows users to take advantage of the benefits of differential signal transmission, such as improved suppression of interference compared to purely single-ended measurements.
