DELTA DVP04PT06PT-S Temperature Measurement
Thank you for choosing Delta DVP series PLC. DVP04/06PT-S is able to receive
4/6 points of RTDs and convert them into 16-bit digital signals. Through
FROM/TO instructions in DVP Slim series MPU program, the data can be read and
written. There are many 16-bit control registers (CR) in modules. The power
unit is separate from it and is small in size and easy to install.
DVP04/06PT-S is an OPEN-TYPE device. It should be installed in a control
cabinet free of airborne dust, humidity, electric shock and vibration. To
prevent non-maintenance staff from operating DVP04/06PT-S, or to prevent an
accident from damaging DVP04/06PT-S, the control cabinet in which DVP04/06PT-S
is installed should be equipped with a safeguard. For example, the control
cabinet in which DVP04/06PT-S is installed can be unlocked with a special tool
or key.
- DO NOT connect AC power to any of I/O terminals, otherwise serious damage may occur. Please check all wiring again before DVP04/06PT-S is powered up. After
- DVP04/06PT-S is disconnected, Do NOT touch any terminals in a minute. Make sure that the ground terminal on
- DVP04/06PT-S is correctly grounded in order to prevent electromagnetic interference.

- I/O Terminal Layout
External Wiring
-
Note1 : Use only the wires that are packed with the temperature sensor for analog input and separate them from other power line or any wire that may cause noise.
Note 2: 3-wire RTD sensor provides a compensation loop that can be used to subtract the wire resistance while 2-wire RTD sensor has no mechanism to compensate. Use cables (3-wired) with the same length (less than 200 m) and wire resistance of less than 20 ohm. -
Note3: If there is noise, please connect the shielded cables to the system earth point, and then ground the
system earth points or connect it to the distribution box.
Note 4: Please keep wires as short as possible when connecting the module to a device whose temperature is going to be measured, and keep the power cable used as far away from the cable connected to a load as possible to prevent noise interference. -
Note 5: Please connect a power supply module and on the temperature module to a system
ground, and then ground the system ground or connect the system ground to a distribution box.

Symbols: O means latched. (Supported with RS485, but does not support when connecting to MPUs.) X means not latched. R means can read data by using FROM instruction or RS-485.
W means can write data by using TO instruction or RS-485.

- Added the RESET function is only for 04PT-S modules with firmware V4.16 or later and not available for 06PT-S. Connect the module power input to 24 VDC and write H’4352 into CR#0 and then turn the power off and on again; all parameters in modules, including communication parameters are restored to factory defaults.
- If you want to use Modbus address in decimal format, you can transfer a hexadecimal register to decimal format and then add one to have it become a decimal Modbus register address. For example transferring the address “H’4064” of CR#0 in hexadecimal format to decimal format, to have the result 16484 and then adding one to it, you have 16485, the Modbus address in decimal format.
- CR#32 communication format settings: for DVP04PT-S modules with firmware V4.14 or previous versions, b11~b8 data format selection is not available. For ASCII mode, the format is fixed to 7, E, 1 (H’00XX) and for RTU mode, the format is fixed to 8, E, 1 (H’C0xx/H’80xx). For modules with firmware V4.15 or later, refer to the following table for setups. Note that the original code H’C0XX/H’80XX will be seen as RTU, 8, E, 1 for modules with firmware V4.15 or later.
