· Product Introduction

The SPE electrical energy signal data acquisition module is meticulously designed based on a new generation of embedded systems. Equipped with an isolated communication interface, it can communicate independently with a PC or PLC, or be networked with multiple communication modules. It also features a transient suppression circuit that effectively suppresses various surge pulses, ensuring reliable operation in harsh environments.

The SPE6-NA series frequency signal acquisition module acquires frequency signals through a single channel and is equipped with an RS485 communication interface. The module uses an internal high-precision timer to acquire data, achieving a resolution of up to 16 bits and a measurement accuracy of better than 0.1%. The power supply, input, and communication output are isolated, making it suitable for collecting a variety of electrical energy signals in industrial settings and meeting the high measurement requirements of industrial sites, medical electronics, security monitoring, smart buildings, smart homes, power monitoring, and process control.

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