CONVERTERS & ISOLATORS
Isolated barriers have several advantages compared to Zener barriers: A Zener barrier is a pass-through device, so it does not isolate the field device from the PLC. Using an isolated barrier eliminates the possibility of a ground loop by isolating the field device from the PLC. ... ground.
In short, an isolated power converter isolates the input from the output by electrically and physically separating the circuit into two sections preventing direct current flow between input and output, typically achieved by using a transformer.
A data logger (also data logger or data recorder) is an electronic device that records data over time or in relation to location either with a built in instrument or sensor or via external instruments and sensors. Increasingly, but not entirely, they are based on a digital processor (or computer).
SIGNAL TRANSMITTERS & TRANSDUCERS
A Signal Converter is a device that converts signals from sensors to industrial current signals, converts analog input signals to analog output signals, normalizes signals, or isolates signals. ... This makes it difficult to input the data directly into control circuits.
Split One Analog Signal into Two Isolated DC Outputs
A trip amplifier is defined as a device that allows an Analog signal to be converted to a Digital output. The digital output controls the variation of a physical unit in a system measured by temperature sensors or normalized signals and operates when the measured value goes outside predetermined limits, energizing or de-energizing the relay controlling devices like valves and actuators.
