Five Reasons Why Using Signal Conditioners Pays Off for You

Signal conditioners from Pepperl+Fuchs
More efficiency with signal conditioners.

You know that signal conditioners convert field signals into standard signals and avoid interference from ground loops - but did you also know that they protect personnel and equipment from dangerous overvoltage?

Discover other useful features of signal conditioners.

1. Filtering of couplings

Signal conditioners protect signal circuits against high-frequency coupling. For example, for drive motors with variable frequency control, the input filter of the signal conditioners filters coupled interference. Thus, measurement and control circuits in environments with high-frequency interference are effectively protected.

2. Protection of field signals in case of failure

Signal conditioners protect the field circuits in the event of a short circuit. Otherwise, the faulty circuit may shut down the entire supply chain and could cause damage to the wiring. Signal conditioners offer short circuit protection for each circuit of the field device. If a single circuit fails, the other circuits are not affected.

3. Protection against surges

Signal conditioners protect personnel and equipment from dangerous voltages. In case of failure, high AC voltages or voltage pulses can enter the measuring circuit. Signal conditioners prevent the passage of high voltages into the control-side loop by galvanic isolation. Personnel and equipment are protected from dangerous high voltages.

4. Reliable signal doubling (signal splitting)

Signal conditioners double input signals. When signals are needed for several parallel outputs, such as in DCS and ESD systems, or data acquisition systems, signal conditioners provide the input signal at the output in parallel. The input signal can be used independently by several systems. In case of system failure the other signal remains available.

5. Potential equalization within a channel

Signal conditioners adapt sources and sinks within a signal circuit. When a field device and a control unit feed current at the same time into the channel, the result is a non-functional circuit. Signal conditioners ensure the potential equalization within the channel. All combinations of current sink, current sources, and voltage sources can be realized.
