This document is an introduction to a certain product, mainly describing its features and characteristics.
This manual describes the AL807 series temperature controller, which supports various thermocouples and Pt100 sensors, offering heating/cooling control, multiple alarm functions, high measurement accuracy and strong interference resistance. It is intended for industrial high‑precision temperature regulation.
The document covers mechanical installation, electrical connections, panel display functions, set‑point adjustment, PID parameter tuning (including auto‑tuning), alarm configuration, and troubleshooting with fault codes. Technical specifications such as power supply range, output types, and sensor measurement ranges are also listed. This manual is written in Chinese.
| Power supply voltage | 92~262V AC, 24V AC/DC |
|---|---|
| Relay output | Normally open, 3A/250V AC |
| Logic level output | 20V/10mA |
The controller can be powered from 92~262 V AC or from a 24 V AC/DC source.
Press the ∧ or ∨ keys while the set‑point is displayed to increase or decrease the value.
Set the TVNE parameter to ON; the controller will begin the PID auto‑tuning process.
