4-20mA signal splitter is the most commonly used device in industrial processes. Control loops in process industries often require an analog standard signal to be processed at two different points, with both devices needing to receive the same signal. To prevent falsified signals without any interference, it is very necessary to galvanically isolate these signals. The VariTrans A 20300 4-20mA signal splitter is an ideal cost-effective solution to the problem. Its input, both outputs, and power supply are decoupled from one another offering 4-Port Isolation.
In addition to “doubling” the analog signal, the can also convert signals if required. The corresponding input and output signals are calibrated and can be selected using DIP switches.
The VariTrans A 20300 can also be used when a particularly high output load is required. Both output signals are not used separately in this case, but are connected in series to form one signal. This doubles the available voltage, making it possible to drive a higher load.
Typical applications include utility energy custody transfer on grid or pipeline; and data recording devices used in conjunction with PLC or DCS for real-time adjustments and historical data recording.
