NCS-TT108F Smart Temperature Transmitter is an eight-channel, DIN-rail-mounted temperature transmitter designed for multi-point temperature measurement in industrial field applications. It supports measurements from various types of resistance temperature detectors (RTDs), thermocouples (TCs), resistors (Ω), and voltage (mV) sensors, and is compatible with the FOUNDATION Fieldbus H1 communication protocol. The product has obtained multiple international certifications, including explosion-proof, PAC, EAC, and FCG, and is widely used in process industries such as petroleum, chemical, power generation, and metallurgy.

The core challenge of HART hardware design lies in how to simultaneously carry a 4-20 mA DC analog signal, a 1200/2200 Hz FSK AC signal, and possible loop supply voltage on the same pair of wires, ensuring that the three do not interfere with each other and meet stringent industrial EMC standards. This chapter starts with the system architecture and analyzes the design key points layer by layer.

In the field of industrial automation, HART (Highway Addressable Remote Transducer) protocol serves as a core technological link connecting traditional analog equipment with modern digital management systems. Having undergone nearly forty years of industrial field validation, HART has become one of the most widely deployed field device communication protocols globally. By using Bell 202 FSK modulation technology, digital communication signals are superimposed on a traditional 4-20mA analog current loop, achieving dual-mode coexistence of " analog transmission + digital communication . " This design allows companies to endow existing equipment with digital capabilities such as remote configuration, real-time diagnostics, and multivariate transmission without interrupting existing control loops or re-laying cables.

The M0310-ACT is Microcyber M-series built-in module, specifically designed for HART communication in electric actuators . Its core function is to build a bidirectional translation bridge between Modbus actuators and HART masters. It features a modular design, making it easy to integrate and deploy.
