RATO has a wide range of signal conditioning modules which include DC voltage, current, AC voltage, current, frequency, Thermocouple, RTD (2, 3 and 4 wire), load cell, potentiometer and electric charge. Outputs for signal conditioning modules can be voltage, current, frequency, timer, counter, relay, resistance or potentiometer and any other specialized outputs with single or multiple isolated outputs
The signal conditioning process includes amplification, filtering, range matching and isolation to make the output suitable for processing after conditioning. The power lines present in the environment will produce noise if the signal is amplified without filtering. Signal amplification performs two important functions: to increase the resolution of the input signal and to increase the signal-to-noise ratio. The commonly used amplifiers in signal conditioning are sample and hold amplifiers, peak detectors, log amplifiers, Instrumentation amplifiers. Signal Isolation is done through magnetic or optic isolation.
Types of devices that are used in RATO?s signal conditioning are signal filters, instrumentation amplifiers, sample and hold amplifiers, isolation amplifiers, signal isolators, multiplexers, Analog to digital converters, digital to Analog converters, frequency converters or translators, voltage converters or inverters, frequency to voltage converters or vice versa, current to voltage converters and charge converters.
