M-Systems 20VS2-3 Hybrid Isolation Amplifiers 20 Series; Isolation Amplifier (for Narrow Span, Input Isolation) Simple Type: Signal Conditioning

Signal conditioners convert a field signal from various sensors into standard signal suitable for processing in PLC, DCS or PC-based systems. They are also used to boost a signal to increase load drive capability, to isolate a signal to stop ground loops. More than 75000 combinations of process signal I/O, power input and mounting configuration are selectable. Additionally, M-System offers the broadest line of signal splitters available. Isolation amplifiers provide signal and power isolation for data acquisition components to protect them from noises present at remote devices.
