The DMD4059 accepts an input from one to four strain gauges, bridge sensors, load cells, or pressure transducers. It filters, amplifies, and converts the resulting millivolt signal into the selected DC voltage or current output that is linearly related to
the input. The full 3-way (input, output, power) isolation makes this module useful for ground loop elimination and signal isolation. The adjustable excitation power supply generates a stable source of voltage to drive from one to four 350 Ω (or greater) devices. Sense lead circuitry is included to cancel the effects of leadwire resistance.
Input, output, excitation and zero offset (up to ±100% of span) are field configurable. Non-interactive zero and span simplifies calibration.
A 20 VDC loop excitation supply for the output can be selectively wired to power passive mA devices. A green input LED and a red output LED vary in intensity with changes in the process input and output signals. An output test button provides a fixed output (independent of the input) when held depressed. The test output level is potentiometer adjustable from 0 to 100% of output span.
