Isolation Amplifiers
DAQP Series Modules
DAQP series modules are dynamic isolation amplifiers with high bandwidth. All are single channel and have an analog ±5 V output. The configuration is done via RS-485 interface. Versions with different convenient connectors for signal connection are available. Models with multi-pin connectors offer sensor supply for single cable sensor connection.
All DAQP series modules are easily exchangeable by the user and thus perfectly suited for flexible instrument solutions. The modules plug into many DEWETRON instruments but are also popular for pure signal conditioning applications.
Key features:
- High isolation up to 1.8 kVRMS
- High bandwidth up to 300 kHz
- ±5 V conditioned signal output
- Easy configuration
The DAQP modules data sheet includes an overview about ALL models and the technical details of each.
