Overview
The SDM-AO4 is a synchronous device for measurement (SDM) that provides four analog outputs. Values in the data logger are transferred to the SDM-AO4 as digital values. The SDM-AO4 then performs a digital-to-analog conversion and outputs an analog voltage signal.
Technical Description
The SDM-AO4 provides four independent, continuous, analog outputs for proportional control or driving strip charts. Measured or processed values in the data logger are scaled to millivolts and transferred to the SDM-AO4 as digital values. The SDM-AO4 then performs a digital to analog conversion and outputs an analog voltage signal. The output voltage level is maintained until updated by the data logger.
SDM Operation
The data logger enables individual modules through an addressing scheme; multiple SDMs (in any combination) can be connected to one data logger. After a module is enabled, it operates independently of the data logger until additional commands are received or results are transmitted.
