DEWE-43A
8-Channel USB Data Acquisition (DAQ) System
DEWE-43A highlights
Universal Analog Inputs
DEWE-43 comes with universal analog inputs that can accept voltage and full-bridge sensors natively. Additionally, IEPE, charge, full and half bridge, RTD, thermocouple, current, and LVDT signals are supported by using our DSI adapters.24-Bit Sigma Delta ADC
DEWE-43A is equipped with 24-bit sigma-delta analog-to-digital converters with an anti-aliasing filter. The analog sampling rate is software selectable up to 200 kS/s per channel.Sensor Power Supply
Each analog channel on the DEWE-43A provides power for sensor excitation.SuperCounter® Inputs
Each counter channel input is capable of three digital inputs, one event counter, encoder, period, pulse-width, duty-cycle, and precise frequency and angle measurement using patented SuperCounter® technology.Isolated CAN Inputs
DEWE-43A includes two high-speed CAN 2.0b channels with 1 Mbit/sec data throughput. Both ports offer additional support for CCP, OBDII, J1939, and CAN output.Fully Synchronized
All input channels - analog, digital, and CAN - are fully synchronized with each other with microsecond accuracy. Multiple devices can be further daisy-chained and synchronized with the same pin-point synchronization accuracy.Isolated Power Supply
DEWE-43A power supply is internally isolated which is eliminating the possibility of ground loops.Software included
Every Dewesoft data acquisition system is bundled with award-winning DewesoftX data acquisition software. The software is easy to use but very rich and deep in functionality. All software updates are free forever with no hidden licensing or yearly maintenance fees.Dewesoft quality and 7-year warranty
