The 1pcs Analog 420mA Signal Isolator provides a simple and reliable way to split and protect a standard 420 mA current loop. It takes a single input current signal and presents two galvanically isolated outputs, allowing two independent receivers to be fed from one sensor without sharing a common electrical ground. Key benefits Protects control systems from noise, surges and ground loops by providing galvanic isolation between the input and the outputs. Delivers two isolated outputs from a single 420 mA input, enabling parallel monitoring, logging, or control without additional signal conditioning. Improves safety and reliability in industrial environments by preventing interference between equipment connected to different parts of the loop. Simple and flexible installation compatible with standard 420 mA current loops, suitable for panel mounting or inline integration in control schemes. Compact and easy to integrate into existing process instrumentation without changing the original sensor or transmitter setup. Key attributes Functionality: analog signal isolator with one input and two galvanically isolated outputs Compatibility: designed for standard 420 mA current loop systems Output configuration: two isolated outputs that reproduce the input signal Isolation: galvanic isolation between input and each output to minimize ground loop and noise problems Size and form: compact singledevice solution suitable for integration in control panels and instrumentation racks Performance: preserves the 420 mA signal while providing dual isolated paths for downstream devices What is included 1 piece signal isolator unit ready for connection to a 420 mA input and two isolated 420 mA outputs Applications and use cases Signal duplication for data logging: feed two data loggers from a single sensor signal while maintaining electrical isolation Redundant measurement or control: supply two PLCs or controllers with isolated current loops to reduce singlepoint failures and ground loop risk Noise and interference mitigation in harsh environments: isolate measurement signals to protect sensitive instrumentation and control equipment from electrical noise or crosstalk Usage notes Connect a standard 020 mA / 420 mA loop to the input terminal and connect two receivers to the two isolated outputs Ensure that both outputs stay within the same current loop range to maintain signal integrity Use in environments where galvanic isolation improves safety and reduces interference between devices This product description reflects the specification of a single input, two output galvanically isolated analog 420 mA signal isolator and aligns with its intended use in industrial process control, measurement, and data acquisition applications.
