A signal conditioner is a device that converts one type of electronic signal into another type of signal, to prepare it for processing. Signal conditioners are used to convert a signal that may be difficult to read by conventional instrumentation. The output signal is then compatible with data acquisition and machine control.
Signal conditioners are traditionally DIN Rail mounted and are used on a DIN Rail bracket. They are very popular in industrial applications since they provide a rugged mounting format. Backplane Mount Conditioners - The backplane style provides the advantage of all output signals being accessible through a single common connector. Backplane signal conditioners are often used with data acquisition systems.
Signal conditioning can perform a wide range of processes required to make sensor output suitable for processing include amplification, filtering, converting, range matching, isolation. Some signal conditioners also provide evaluation and measurement. The input from a sensor is connected to the signal conditioner, which is then able to convert the specific input type into a signal that produces the necessary output type for the instrumentation used. The input signals and output signals can be voltage or current, depending on the device.
