...precise control with rapid safety checks to protect your shaker and your products. Designed with this in mind, the next generation of controllers from Brüel & Kjær spans the whole range of aerospace and space vibration test applications. Using dual, parallel 24-bit A/D and DSP technology, VC-LAN Vibration Controller Types 7541 and 7542 offer advanced performance and flexibility, with a 130 dB input range and fast loop times.

The VC-LAN controllers are modular and expandable, offering up to 64 input channels for control and limiting. The high channel count enhances safety and analysis for complex, fragile structures such as satellites. Special vibration control software provides random control including sine-on-random and random-on-random, swept-sine control including tracked resonance dwell, shock vibration control including classical waveforms, transient replication, SRS synthesis and control, and time-waveform replications. Applications are specifically tailored to each type of vibration test to reduce learning time and make it easy to get results quickly.

The controllers integrate fully with Brüel & Kjær’s LAN-XI data acquisition hardware to provide simultaneous and integrated data acquisition, and to make over 1000 channels of abort monitors possible. PC connectivity is via LAN interface, which allows wireless operation, reduces cabling, and allows the controller to be placed close to the shaker. This facilitates centralised control of multiple controllers remote from the vibration table test stations, so the entire system can be supervised and analysed remotely.
