Signal Splitters / Output Signal Distributors
A signal splitter is a module that takes a single input signal — analog or digital — and replicates it into multiple identical output signals. This makes it possible to feed the same sensor signal simultaneously to several control, regulation or display systems without loss of signal integrity or the need for additional sensors. Splitters are often designed as DIN-rail devices, offering easy wiring, flexible integration and stable signal distribution inside the control cabinet.
Signal splitters are used when the same measurement signal needs to be available at multiple destinations — for example a PLC, a display panel and a supervisory system — helping to minimize wiring, avoid signal loss or interference, and maintain a clean system layout. Some splitters provide galvanic isolation between input and outputs to avoid ground loops or potential differences.
Questions & Answers on Signal Splitters
What is a signal splitter?
A signal splitter receives one input signal and produces multiple identical output signals, so that the same signal can be distributed to several consumers at once.
When is a signal splitter used?
Whenever a sensor’s signal needs to be sent to more than one device — for instance a PLC, a display unit, and a monitoring system — without adding extra sensors.
Which signal types can a splitter handle?
Depending on the model, analog signals (e.g. 4 … 20 mA, 0 … 10 V), digital or binary signals, or pulse signals can be split.
How many outputs does a typical splitter provide?
That depends on the specific device — commonly two to four identical outputs are available; some models even offer more. Each output carries the same signal as the input.
Does using a splitter affect signal quality?
With a high-quality splitter the signal remains unchanged regarding scaling, linearity and accuracy. Proper wiring and adherence to output load limits ensure stable signal quality.
Does a splitter provide galvanic isolation?
Some splitters include galvanic separation between input and outputs. This helps to avoid potential differences and ground loops, especially where long wiring or different grounding references exist.
Is an external power supply required?
It depends on the type. Passive splitters distribute the signal without additional power. Splitters with galvanic isolation or signal conditioning normally require their own supply, commonly 24 V DC.
How is a splitter mounted and wired in a control cabinet?
Splitters are usually mounted on a DIN rail. The input signal connects to the input terminals; the outputs are wired to the respective consumers. Clear separation of signal and power wiring simplifies maintenance and diagnostics.
Which applications are suited for signal splitters?
Parallel signal distribution to control, monitoring and display systems, redundant system setups, retrofits, logging, modular panels, and any situation where a sensor signal is needed in multiple places.
Are there any limitations when using splitters?
Yes — each output must stay within the splitter’s load specification. If many outputs or long cable runs are used, a splitter with own power supply and galvanic isolation may be required to avoid signal degradation or interference.
