Delta DVP04PT-S & DVP06PT-S Temperature Measurement Module

Instruction Sheet

Introduction

Thank you for choosing Delta DVP series PLC. The DVP04/06PT-S is designed to receive 4/6 points of RTDs and convert them into 16-bit digital signals. Data can be read and written through FROM/TO instructions in DVP Slim series MPU programs. These modules feature numerous 16-bit control registers (CR) and have a separate, compact power unit for easy installation.

Installation and Safety Precautions

General Installation: The DVP04/06PT-S is an OPEN-TYPE device and must be installed in a control cabinet that is free from airborne dust, humidity, electric shock, and vibration. To prevent unauthorized access and potential damage, the control cabinet should be secured with a special tool or key.

Electrical Safety:

DO NOT connect AC power to any I/O terminals, as this can cause serious damage.
Always double-check all wiring before powering up the DVP04/06PT-S.
After disconnecting power, do not touch any terminals for one minute.
Ensure the ground terminal is correctly grounded to prevent electromagnetic interference.

External Wiring

Wiring Notes:

Use only the wires provided with the temperature sensor for analog input. Keep these wires separate from other power lines or any wires that might cause noise.
3-wire RTD sensors offer a compensation loop to subtract wire resistance, while 2-wire RTD sensors do not. For 3-wire connections, use cables of the same length (less than 200 m) with a wire resistance of less than 20 ohms per wire.
If noise interference is significant, connect shielded cables to the system earth point and then ground the system earth point or connect it to the distribution box.
Keep wiring as short as possible when connecting the module to the temperature measurement device. Route power cables away from cables connected to loads to prevent noise interference.
Connect the power supply module's power input terminal and the temperature measurement module's system ground terminal to the system ground, then ground the system ground or connect it to the distribution box.
