This manual describes the Baelz 6490B family of temperature controllers. It includes product specifications, wiring diagrams, a description of the setting interface, data tables, alarm configuration and communication options such as Modbus/RS‑485.
Key sections cover input voltage options, temperature measurement ranges, alarm types, and detailed parameter tables for each model variant. The document is intended for installers and end‑users who need to configure and maintain the controllers in industrial automation environments. This manual is written in Chinese.
| Input voltage (AC) | 230 V AC, 115 V AC, 24 V AC |
|---|---|
| Temperature range (2.4 V input) | 0 °C – 300 °C (0.1 % accuracy) |
| Temperature range (2.2 V input) | 0 °C – 400 °C (0.1 % accuracy) |
The controller can be powered from 230 V AC, 115 V AC or 24 V AC.
With a 2.4 V sensor the range is 0 °C to 300 °C, and with a 2.2 V sensor it is 0 °C to 400 °C, both with 0.1 % accuracy.
Alarms can be set to four different forms (A‑D) that trigger on high, low, out‑of‑range or sensor failure conditions.
Yes, the device includes an RS‑485 Modbus interface for remote monitoring and control.
