This module is engineered for ultra-high-precision acquisition of weak millivolt thermoelectric potential signals from industrial thermocouples, fully compatible with K, S, B, E, J, T, R and all mainstream standard thermocouple types. It integrates military-grade ultra-low-noise precision instrumentation amplifiers, multi-point distributed self-learning cold junction compensation, three-stage cascaded reinforced galvanic isolation and brand-new full-range adaptive temperature conversion algorithm, converting tiny thermocouple voltage signals into ultra-low-drift, high-repeatability digital temperature data and uploading to the DCS main controller.

Compared with G01~G05 predecessors, the G06 revision equips ultra-wide temperature stabilized low-drift amplifier chips to drastically suppress zero drift and gain drift under extreme ambient temperature fluctuations; upgrades multi-point cabinet cold junction real-time self-calibration algorithm to eliminate measurement deviation caused by uneven internal cabinet temperature; adds multi-layer composite EMI/EMC suppression circuits, significantly strengthening anti-interference capability for ultra-long-distance thermocouple wiring in heavy industrial environments with intense electromagnetic radiation from inverters, high-voltage switchgears and large rotating machinery. Each signal channel is equipped with an entirely independent isolation loop to thoroughly eliminate cross-channel signal crosstalk and mutual interference.

The circuit board adopts multi-layer high-temperature resistant FR-4 industrial PCB with a 360° fully enclosed electromagnetic shielding structure. Every signal channel achieves 1000V AC/DC reinforced galvanic isolation between field wiring terminals and internal logic circuits, effectively blocking surge impact, common-mode noise and high-frequency electromagnetic interference in thermal power, petrochemical, metallurgical and other heavy industrial sites.

All finished boards pass full-lifecycle strict factory reliability verification, including 72-hour high-low temperature cyclic aging test, full-channel full-range thermocouple precision calibration, long-duration full-load MRC Link bus continuous burn-in test, and comprehensive sensor open-circuit, short-circuit and wiring fault simulation test. It supports single-slot hot-swappable online replacement without shutting down the entire DCS system, and integrates multi-layer comprehensive hardware protection functions: surge suppression, overvoltage protection, overcurrent protection, reverse polarity prevention and short-circuit protection. Independent LED diagnostic indicators separately display power supply status, bus communication link status and single-channel thermocouple fault alarm information, enabling fast on-site fault location and troubleshooting, greatly improving long-term measurement accuracy and uninterrupted stable operation performance for high-temperature furnaces, kilns and pipeline temperature monitoring links.
