DTA is the DTA series temperature controller from Delta, with options of relay output, voltage pulse output, current output, RS-485 communication function, support multiple temperature sensors.
This manual covers safety precautions, installation steps, and wiring guidelines for the Delta DTA series temperature controllers (models 4848, 4896, 9648, 7272, 9696). It explains how to connect power, select and mount temperature sensors, and configure control modes (PID, ON/OFF, manual).\n\nDetailed sections describe alarm output settings, RS‑485 communication parameters, register map definitions, and troubleshooting tips. The document also lists technical specifications such as input voltage, power consumption, IP rating, and environmental limits. This manual is written in Chinese.
