DTB series temperature controller is an open type temperature controller launched by Delta, with 4824, 4848, 4896, 9696 four specifications. It can choose relay output, voltage pulse output, DC current output, linear voltage output, and can also choose CT, EVENT input, valve position control and other optional accessories.
This manual provides detailed instructions for installing, wiring, and configuring Delta DTB series temperature controllers. It includes safety precautions, power requirements, panel dimensions, output options, sensor selections, and environmental limits.
The document also describes alarm functions, PID programming, valve‑position control, and Modbus (ASCII/RTU) communication settings, along with register maps for parameter configuration and troubleshooting. This manual is written in Chinese.
