TRS03

TRS04 true rms output Three-phase Rogowski coil current sensor/current transmitter

The combination of the rogowski coil and integrator can achieve 90° phase shift compensation and frequency equalization, so that the Rogowski coil output is in phase with the primary current and is frequency independent to adapt to more application scenarios. TRS03 series integrator can output industry standard true rms 4-20mA, 0-20mA, 0-5V, 0-10V, ideal for process control, status alarm or system monitoring. Commonly used with SCADA systems, PLCS, data loggers and protection devices.

Features include:

Three-phase measurement
Fully isolated measurement
True rms output
Insulated plastic housing, UL94-V0
Certified CE and RoHSIII compliant
DIN rail mounting
Small size

Applications:

SCADA systems
PLC
Data loggers
Protection devices

Why use 4-20mA/0-20mA transmitter?

Current output transmitters are key devices in industrial automation and control systems, used to transmit sensor signals over long distances without being affected by electrical noise. The most commonly used standards include 0–20mA and 4–20mA current output ranges. Many industrial controllers, data acquisition systems, and programmable logic controllers (PLCs) are designed with 4-20mA signals as standard inputs. It provides an easy-to-use solution for third-party power meters or other devices.
