DVP04TC-S Temperature Measurement Module is a product of Delta DVP series. It can accept external 4-point thermocouple temperature sensors (J or K type) and convert them into 14-bit digital signals. Through DVP-PLC SS/SA/SX/SC host program to read and write data in the module, the module has 49 CR (Control Register) registers, each with 16 bits.
This manual describes the DVP04TC-S temperature measurement module, which converts signals from up to four J‑type or K‑type thermocouples into a 14‑bit digital value. It can be connected to Delta DVP‑PLC series via RS‑485 and supports both Modbus ASCII and RTU modes.
The document covers safety precautions, physical layout, terminal assignments, wiring guidelines, register definitions, communication settings, and programming examples for reading and writing module data from a PLC. This manual is written in Chinese.
