The LORD MicroStrain® WSDA-Base-101-LXRS Wireless Analog Output Base Station supports all data acquisition sessions between wireless nodes and host computers including Synchronized Sampling (both Continuous and Burst modes), Armed Datalogging, Datalogging, Streaming and Low Duty Cycle. As an integral feature, the WSDA-Base-101-LXRS has an analog output back panel that supports analog data acquisition equipment (DAQs). Up to 8 sensor channels from one or multiple wireless nodes can be fed into a DAQ with simultaneous digital feed into a PC, or into a DAQ with the PC removed (stand-alone configuration). Each channel on the back panel has a 0 to 3 volt range representing the particular sensor’s full scale output. In some environments and with some equipment, the 0 to 3 volt range is not appropriate; many types of programmable logic controllers (PLCs) and DAQs have only current loop inputs, are therefore incompatible with voltage output sensors, and require a 4 to 20 mA output range to operate. This technical note demonstrates how to convert the 0 to 3 volt output to a 4 to 20 mA output using a third party converter and assumes familiarity with the WSDA-Base-101-LXRS, LORD MicroStrain wireless nodes and Node Commander software.
