Ascent automation offers digital signal converters and isolators which are simple to use. They have connections for power supply, input signal and output signal. The output signal is galvanically isolated from the input power supply and also the input signal. They are mainly used for isolation of field signals from the central process computer or dcs system. Good components and sound design make the isolators very reliable and accurate. The signal converters/isolators also have good linearity and repeatability.
