USB front-end convenience has grown up with the DEWE-50-USB2-8, gaining real signal conditioners with HIGH ISOLATION, synchronous digital and CAN bus inputs - and the best data acquisition software in the world: DS-7.
- Accepts any 8 DAQ / PAD/ HSI series plug-in signal conditioners
- 8 channels with 200 kS/s/ch sampling
- 24-bit resolution, automatic anti-aliasing filtering
- 2 synchronous counters / 24 TTL digital inputs
- 2 x CAN bus inputs
- Runs from 6-26 VDC (includes AC adapter)
- Includes DS-7-PROF software
Finally, real ISOLATED signal conditioning has come to the USB tethered data acquisition system. Choose any combination of our DAQ / HSI and PAD series plug-in signal conditioners.
A popular option for this model is the installation of 8 BNC connectors on the rear panel, with the analog input signals, fully conditioned on them (±5V full-scale). See the photo at right.

Top Applications
- Energy test (with isolated DAQ and HSI modules)
- Industry test (ideal for the factory floor)
- Noise and vibe test (with DAQP-ACC and -CHARGE modules)

High-speed CAN BUS interfaces
Locking USB connector
Accepts any combination of 8 of our DAQ, HSI and PAD series plug-in signal conditioning modules! These are ISOLATED signal conditioners for making measurements even in "unfriendly" and challenging measuring environments.
Two high speed CAN BUS interfaces are built into the back of the system, fully supported in the software. Add hundreds of CAN parameters to your recordings.
Don't worry about the USB cable pulling out of the back of the chassis -- it screws in securely using our unique hardware. Accidental disconnection from our hardware is impossible.
There are several DEWE-50 models available. The hardware is the same, but the edition of data acquisition software included varies, from the Standard Edition to the Dynamic SIgnal Analysis version.
