Bộ chuyển đổi và khuếch đại tín hiệu, Signal Conditioning Modules, The main aim of Signal Conditioning Module is to convert input signals from a primary sensor signal to unified standard ranges.
Signal Conditioning Modules and normalizers represent the essential link between a great world of sensors, execution units and systems of data collection and control on the basis of computers and controllers. Being an integral part of the measuring channel they secure informational compatibility for all system.
Normalizers convert signals of direct and alternating current, current loop, thermocouples, resistive thermometers, tension sensors, resistors and potentiometers, etc. into the unified signals of standard range. For the analog signals this is usually either the ranges between 0…5 V, 0…10 V, 0…20 мА, 4…20 мА, or the current loop. For discrete signals these are TTL-level signals with a range between 0…5 V.
