Absolute Process Instruments Signal Conditioners
Signal conditioners are devices that convert one type of electronic input signal into a different type of output signal. The input signals received from sensors are amplified, filtered and isolated into a more easily read output signal for processing. Many applications involve measurements from sensors that need signal conditioning before the instrument can accurately and effectively measure the signal. Functions of signal conditioners include: conversion, linearization and amplification.
Absolute Process Instruments Signal Conditioners are available in two designs. The first is a 1 Channel Signal Converter/Isolator/Transmitter Channel Plug-in with 1 input signal and 1 output signal and 3-way isolation for each signal and power. The second is a 2 Channel Transmitter and Isolator with factory-configured 2 frequency input signals and 2 independent DC output signals. The power supply voltage (85-265 VAC), inputs and outputs, are all independent. Each input is filtered, amplified, and isolated. Convert and isolate dual output transmitters. Two independent channels with full isolation with zero and span for each output.

Signal Conditioning: Isolators, Converters, Amplifiers and Splitters
Signal isolators are used to protect sensitive equipment, such as PLCs, from potential hazards that may originate from devices they are connected to, such as sensors or transmitters. Isolators can also be used to filter any noise that might arise from disturbances along the signal path back to the PLC.
Signal converters take one type of signal and change it to something else. For example, a signal converter can interpret an RTD signal and convert it into something that a PLC can understand.
Signal amplifiers increase the resolution of an input signal, allowing for more accurate and detailed data to be sent to the controller, enabling better monitoring and control of devices. Another important function that amplifiers perform is increasing the signal-to-noise ratio.
Signal splitters do not change the signal, but allow the signal to be sent to more than one location. For example, a signal splitter can be used to send data to two different PLC’s without any signal degradation.
