DVP04PT-H2 is able to receive 4 points of resistance temperature detectors (PT100, PT1000, NI100, and NI1000) and convert them into 16-bit digital signals. Besides, through the user of FROM/TO instructions in DVP-EH2 MPU program, the data in DVP04PT-H2 can be read or written. There are 49 16-bit control registers (CR) in it. DVP04PT-H2 displays temperatures in Celsius (resolution: 0.1°C) and Fahrenheit (resolution: 0.1°F).
The DVP04PT-H2 module receives up to four resistance temperature detector (RTD) inputs (PT100, PT1000, NI100, NI1000) and converts them to 16‑bit digital signals. It can be read or written via FROM/TO instructions in a DVP‑EH2 PLC program and supports RS‑485 communication in ASCII or RTU mode.
The manual provides electrical specifications, installation and wiring instructions, control register descriptions, and PID control settings. It also outlines environmental limits, isolation requirements, and error status codes for safe and reliable operation.
