OMEGA Engineering, Inc. Universal Signal Conditioning Module DR900

The DR900 Universal Signal Conditioning Module can isolate and convert over 100 combinations of analog signal ranges. The DR900 converts and transmits signals linearly proportional to the input, while the DR900-SQRT transmits the scaled square root of the input signal. This allows the DR900-SQRT to provide a signal that is linear to flow rate in applications utilizing a differential pressure transducer.DIP switch range selection eliminates the need to order and stock different modules for each input and output signal range, and allows quick and convenient setup for over 100 standard signal conversions. By utilizing the Field mode of calibration, the user can customize the input and output scaling for odd applications, including reversal of the output relative to the input. In addition to the conversion capabilities, the DR900 modules feature optically isolated Input/Output signal circuits and transformer isolated Power to Input and Power to Output circuits.The modules' overall full scale accuracy typically exceeds 0.05% depending upon range selection and scaling. The microprocessor based design provides ease of field scaling and the onboard E2PROM stores scaling values for future recall. Both models come factory precalibrated for all input and output ranges. Factory or custom field scaling can be selected by a simple mode switch change.
