· Product Introduction

SPS Series Resistance Signal Isolators utilize industrial-grade 32-bit processors and high-speed optocoupler isolation to convert input resistance signals into isolated linear voltage or current outputs. The transmitter module's output rapidly tracks input signal variations, making it widely applicable in power, railway, telecommunications, PLC-based measurement and control systems, and various automation control systems.

SPS6-NC Series Resistance Transmitters feature precision internal design with constant voltage or current excitation methods for signal acquisition. With full electrical isolation among power supply, input, and output circuits, these transmitters offer high accuracy, high isolation, high speed, and low drift characteristics. They effectively resolve issues such as common-mode interference, electrical isolation, and signal standardization during high-speed transmission of sensor, transmitter, or instrument signals, making them particularly suitable for high-speed transient waveform acquisition, harmonic analysis, and rapid monitoring and alarm applications.

This product requires an independent power supply and is mounted on a standard 35mm DIN rail, offering simple on-site installation and flexible use, adapting to a variety of field applications.
