Differential AmplifiersMDAQ Series Modules
MDAQ series modules are dynamic differential signal amplifiers with high bandwidth.
All are multi-channel and have an analog voltage output. The configuration is done via RS-485 interface. Models with multi-pin connectors offer sensor supply for single cable sensor connection. | Key features:
|
MDAQ series modules are cost-effective and space saving, thus the ideal solution for applications requiring hundreds of dynamic input channels. The modules fit into many DEWETRON instruments.
Configuring MDAQ inputs
MDAQ modules are configured according a building block system. The MDAQ-BASE, the “motherboard” holds up to two MDAQ-SUB modules.
This MDAQ-BASE defines whether the conditioned signal output is ±5 V or ±10 V. A range of MDAQ-SUB modules define the supported input signals. Finally a filter board MDAQ-FILT can be added.
The MDAQ module datasheets includes a nice overview about all models and the technical details of each.
