REX-D100, REX-D400, REX-D700, REX-D900 are temperature control instruments produced by REX company. They adopt PID control algorithm, with high precision, high stability and high reliability.
This manual describes the preparation steps, environmental requirements, and installation procedures for the RKC D series thermostat (models D100, D400, D700, D900). It covers proper wiring, input range settings, and safety precautions such as using fuses and shielding against interference.
The document also explains the display layout, button functions, and the six operating modes (PV/SV, operation, engineer, engineer‑set, configuration, and alarm settings). Detailed parameter tables provide ranges and default values for inputs, outputs, PID control, and alarm configurations. This manual is written in Chinese.
| Power Supply Voltage | 100‑240 V |
|---|---|
| Operating Temperature Range | -40 °C to 85 °C |
