User manual for the Yao Yi XMT-JK808 series temperature controller, covering specifications, operation, wiring and troubleshooting.
The XMT-JK808 series is an intelligent temperature controller with eight independent channels, each configurable for set‑point, PID parameters and alarm functions. It is controlled by a microcontroller, offers low power consumption, compact size and reliable operation for industrial temperature and process control.
The manual provides technical parameters, panel description, internal parameter settings, step‑by‑step operation instructions, self‑tuning procedure, wiring diagrams, fault analysis and warranty information to help users install, configure and maintain the instrument. This manual is written in Chinese.
| Input Types | CU50, PT100, K, E, J |
|---|---|
| Measurement Accuracy | ±0.5% F.S ±1B, cold‑junction error ≤±2℃ |
| Sampling Period | 0.5 s |
| Main Relay Output | AC 220 V / 5 A (resistive) or AC 220 V / 0.3 A (inductive) |
| Alarm Relay Output | AC 220 V / 1 A (resistive) |
| Solid‑State Relay Trigger | Current ≥15 mA, Voltage ≥9 V |
| Power Supply | AC 85 V ~ 242 V, 50/60 Hz (switching) |
| Operating Environment | Temperature 0 ~ 50 ℃, Humidity ≤85 % (non‑corrosive, low EMI) |
The controller accepts CU50 thermocouples, PT100 resistance temperature detectors, and K, E, J thermocouple types.
Set the channel’s HY parameter to 0.5‑1, set AT to 1, then the instrument enters self‑tuning; after three output cycles it calculates and saves new P, I, D values.
