This document introduces the features and characteristics of DVP08TC-H2 temperature transmitter, including electrical specifications, installation and wiring, programming and instructions.
The DVPO8TC-H2 is an open‑type temperature measurement module for PLC systems. It accepts up to eight thermocouple inputs (J, K, R, S, T, E, N types) with a voltage range of 0‑150 mV and provides 24‑bit digital output (0.1 °C/0.1 °F resolution). The module is powered by 24 VDC and communicates via RS‑485 with selectable baud rates.
The instruction sheet details mechanical dimensions, DIN‑rail mounting, terminal layout, wiring recommendations, power and environmental specifications, as well as the full list of 49 control registers. Safety notes emphasize proper grounding, avoiding connection of AC mains to I/O terminals, and keeping wiring short to reduce electromagnetic interference.
