SIGnal Workbench
Flexible, programmable signal conditioning and fault insertion solutions
What is SIGnal Workbench?
Concurrent’s family of SIGnal Workbench products provides flexible, programmable signal conditioning solutions for a wide range of automotive, aerospace and data acquisition applications. SIGnal Workbench is ideal for hardware-inthe-loop test stands and dynamic data processing and monitoring systems for engines and rotating machinery.
SIGnal Workbench is a complete solution that can provide everything needed for high-cycle testing: realtime computer system, data acquisition I/O cards, programmable signal conditioning, cabling and powerful GUI test software for data acquisition control, management, display and post-test analysis. Together with Concurrent’s SIMulation Workbench modeling software, SIGnal Workbench offers a powerful solution for ECU and other subsystem testing that require fault insertion. SIGnal Workbench’s programmable signal conditioning hardware is available separately with a control API for real-time applications that require analog input conditioning.
Non-Programmable Signal Conditioning Modules
The SIGnal Workbench non-programmable signal conditioning (NPSC) line of low cost-per-channel signal conditioners is designed for automotive, aerospace and general purpose industrial applications. Low power modules support sixteen channels. High power modules support eight channels. The modules can be DIN rail mounted for small channel count systems or installed in a compatible 3U 21-slot DIN chassis. Optionally, up to four NPSC modules can be installed in a 1U rack mount chassis via special quotation.
Many applications do not require fault insertion and utilize dedicated conditioning requirements for each channel that are rarely changed. The non-programmable conditioners save the expense of a chassis controller and backplane as well as the software products that are required for programmable conditioners. The NPSC modules are configured using jumpers to set gain or voltage level parameters per channel.
Catalog
The CQ9500TR-08 Conditioning Module features 32 galvanically isolated transformer channels and is intended to interface to AC signal applications requiring isolation such as LVDT, RVDT, synchro and resolver position sensors and simulators. For simulation applications, the module is intended to support eight excitation input channels and 16 output channels providing for eight dual output feedback channels; Va/Vb or sin/cos. The signal path is reversed for position sensing applications. All external channels are differential.
