cDAQ
cDAQ is a new product family of rugged, mobile, CAN based data acquisition providing a flexible distributed network of HBM world class signal conditioning in any environment and weather condition. Engineered to operate within severe temperatures ranges of -40 to 125 °C with an IP 67 protection class rating; the compact cDAQ modules allow users to take measurements directly in the most difficult test objects. These can include engine enclosures, gearboxes, pumps, power generation, and many industrial applications. This reduces installation time, cabling, and test set-up while lowering overall product testing costs.
Overview
The flexible cDAQ modules are compatible with any CAN ISO 11898 2.0B-based system or vehicle network and have a selectable baud rate from 20 kbps to 1 Mbps. Connecting multiple modules through the CAN bus allows for nearly unlimited channel counts, covering great distances up to 250 M.1 cDAQ modules are powered from a user-friendly DC power source from 8 to 36 volts. Once power is applied to the first module, it is distributed through the rest of the network.
Although well-matched with any CAN network, cDAQ modules are optimally designed to interface with the SoMat eDAQ or eDAQlite. A single module can be powered directly from the Vehicle Network Communications layer (ECOM or ELCOM), a hardware query self recognizes the modules in the systems.
The cDAQ-ITC (Isolated Thermocouple) is available in 16-channel configurations for K-, J- or T-type thermocouples. Each channel has individual cold junction compensation fully isolated up to 500 V; with an accuracy of +/-0.5°C. Selectable sample rates are available for each channel from 0.1 to 15 Hz. The cDAQ-ITC also has digital and analog filtering to remove high frequency signal components above 50 Hz and notches at 50 Hz and 60 Hz to prevent aliasing at the power line frequency bands.
