How do you Split a 4-20 mA Signal?
Splitting a signal is a process commonly performed in electronic and communication systems, it involves creating multiple copies of the same signal so that it can be used in different parts of a system simultaneously. Several devices are used to split signals including passive splitters, active splitters, transformers, signal relays, signal multiplexers, and distribution networks. Passive splitters use passive components to divide into multiple paths without amplification. Active splitters use active electronic components to split while maintaining signal strength and quality. Transformers are electrical devices that use magnetic fields to transfer energy between circuits. Signal relays are electrically operated switches that split signals by routing them to different paths. Signal multiplexers combine multiple input signals into a single output or input signal. Distribution networks are designed to distribute signals to various destinations using splitters, amplifiers, and relays.
Acromag offers a selection of process current signal splitter products that replicate and distribute signals effectively in process control, automation, and other industrial settings where signal integrity is critical. These products ensure accuracy and integrity with built-in signal conditioning.
