· Product Introduction
The SPT temperature 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 surges, ensuring reliable operation in harsh environments.
The SPT1060-MC series thermocouple data acquisition module collects 2/4/6 thermocouple signals and is equipped with an RS485 communication interface. It utilizes an advanced 24-bit delta-sigma high-precision digital-to-analog converter, achieving measurement accuracy better than 0.1% and a temperature display resolution of 0.1°C. The power supply, input, and communication output are isolated, making it suitable for collecting a variety of temperature signals in industrial settings. It meets the high measurement requirements of industrial sites, medical electronics, security monitoring, smart buildings, smart homes, power monitoring, and process control 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.
