SPT1080-WC 8 Channel Thermocouple Acquisition Module

· Product Introduction

The SPT temperature data acquisition module is meticulously engineered based on a new generation of embedded systems. It features an isolated communication interface, allowing it to communicate individually with a PC or PLC, or to be networked with multiple communication modules. Furthermore, the module is equipped with a transient suppression circuit, which effectively suppresses various surge pulses, ensuring reliable operation in harsh environments.

The SPT1080-WC series thermocouple data acquisition module collects 4 or 8 channels of thermocouple signals and is equipped with an RS485 communication interface. Utilizing an advanced 24-bit Delta-Sigma high-precision analog-to-digital converter, the module achieves a measurement accuracy better than 0.1% and a temperature display resolution of 0.1°C. It features triple isolation between the power supply, inputs, and communication output. It is suitable for acquiring various temperature signals in industrial settings and meets the requirements for high-precision measurement applications, including industrial sites, medical electronics, security monitoring, intelligent buildings, smart homes, power monitoring, and process control.

This product requires independent power supply and adopts DIN 35mm standard rail mounting, enabling simple field installation and flexible deployment for various application environments.
