Product Introduction: 16710-25
The 16710-25 is a Loop-Powered Signal Isolator/Converter. This device is a fundamental component in industrial process control and instrumentation systems. It is designed to accept a standard 4-20 mA input signal from a field transmitter or sensor and provide electrical isolation, converting it into a clean, isolated, and reliable 4-20 mA output signal. Being "loop-powered" means it operates directly from the energy in the input current loop itself, requiring no separate power supply. This simplifies installation, reduces wiring costs, and is ideal for applications where space and power are limited.

Application Scenarios
This loop-powered isolator is widely used across various industries to ensure signal integrity and system safety.
Ground Loop Elimination:
Installed to break ground loops that can cause signal distortion and measurement errors in systems where the sensor and receiver are at different ground potentials.
Intrinsically Safe (IS) Barriers:
Used in hazardous areas (e.g., chemical plants, refineries) to provide isolation between safe and hazardous areas, preventing dangerous energy from reaching the field.
Signal Protection:
Protects sensitive control system inputs (like PLC or DCS cards) from voltage transients, noise, and faults originating in the field wiring.
Process Industry (Water/Wastewater, HVAC):
A cost-effective and simple solution for isolating 4-20 mA signals from flow, pressure, and level transmitters in general process applications.
Retrofitting and System Upgrades:
Easily integrated into existing control panels to add isolation capabilities without the need for additional power wiring, simplifying retrofits.
