ENGINEERING HIGHLIGHTS

Dual-Deck Modular Architecture

Separates the high-voltage 3000W switching relay power base from the front-panel 4-digit digital display and tactile key MCU daughterboard, isolating electrical noise and maximizing heat dissipation.

Dual-Mode Heating & Cooling Logic

Configurable firmware accommodates positive-coefficient heating elements (ovens, water tanks) or compressor-based cooling loads (refrigeration, chillers) with customizable start-delay protection.

Precision Hysteresis & Offset Calibration

Features 0.5°C to 5.0°C programmable return difference to prevent relay chattering and mechanical wear, coupled with digital temperature offset calibration to eliminate probe lead resistance errors.

Heavy-Duty Industrial Terminals

Equipped with flame-retardant screw terminal blocks rated for continuous high-current industrial wiring, supporting rapid field wiring and secure connection to external sensor probes and loads.
