· Product Introduction

SPS Series Signal Isolators are meticulously engineered based on a new-generation embedded system design. Utilizing high-speed optocoupler isolation, they convert input voltage/current signals into isolated, linear voltage/current outputs. The transmitter module's output signal rapidly tracks changes in the input signal, making it widely applicable in power, railway, telecommunications, PLC measurement and control systems, and various automation control systems.

SPS9-ND Series Digital High-Speed DC Signal Transmitters feature internal electrical isolation among the power supply, input, and output circuits. Equipped with TI-specific high-speed ADC chips, the modules employ an advanced Successive Approximation Register (SAR) high-precision analog-to-digital converter with a resolution of up to 16 bits and a measurement accuracy better than 0.05%. These transmitters offer high precision, high isolation, high speed, and low drift, effectively addressing common-mode interference, electrical isolation, and signal standardization during high-speed transmission of sensor, transmitter, or instrument signals. They are particularly suitable for high-speed transient waveform acquisition, harmonic analysis, 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.
