Delta Electronics DVP Series PLC DVP04TC-H2 Instruction Manual

Warning
Please read this instruction sheet carefully before use.
Switch off the power before wiring.
DVP04TC-H2 is an OPEN-TYPE device and therefore should be installed in an enclosure free of airborne dust,
humidity, electric shock and vibration. The enclosure should prevent non-maintenance staff from operating the device
(e.g. key or specific tools are required to open the enclosure) in case danger and damages on the device may occur.
DO NOT connect input AC power supply to any of the I/O terminals; otherwise serious damage may occur. Check all
the wiring again before switching on the power.
DO NOT touch any terminal when the power is switched on.
Make sure the ground termnial is correctly grounded in order to prevent electromagnetic interference.
Keep the wire as short as possible between RTD and PLC and the power wire as far away as possible from I/O wire
to prevent interference.
When setting the
thermocouple temperature sensor mode, please make sure that the setting of CR#1 is correct, or it will cause
serious errors.
Introduction
Model Explanation & Peripherals
Thank you for choosing Delta's DVP series PLC. DVP04TC-H2 is able to receive 4 points of external
thermocouple temperature sensors (J-type, K-type, R-type, S-type, T-type) and convert them into 14-bit
digital signals. Besides, through FROM/TO instructions in DVP-EH2 MPU program, the data in
DVP04TC-H2 can be read or written. There are 49 16-bit control registers (CR) in DVP04TC-H2.
DVP04TC-H2 displays temperatures in Celsius (resolution: 0.1° C) and Fahrenheit (resolution: 0.18° F).

*1: The wiring used for analog input should adopts the connection cable or shielding cable of thermocouple temperature sensor
J-type / K-type / R-type / S-type / T-type and should be separated from other power cable or wirings that may cause interference.
The screw torque of the terminal should be 1.95 kg-cm (1.7 in-lbs).
*2: Terminal SLD is the ground location for noise suppression.
*3: Please connect the terminal on both the power module and DVP04TC-H2 to the system earth point and ground the system
contact or connect it to the cover of power distribution cabinet.
Note: DO NOT wire empty terminal . Use 60/75°C copper conductor only.

CR#0 ~ CR#127: The corresponding parameter address H'4096 ~ H'4115 are for users to read/write data by
RS-485 communication. When using RS-485, the user has to separate the module with MPU first.
1. Modbus ASCII/RTU communication protocol: ASCII data format (7-bit, even bit, 1 stop bit (7, E, 1)); RTU
data format (8-bit, even bit, 1 stop bit (8, E, 1)).
2. Function: H'03 (read register data); H'06 (write 1 word datum into register); H'10 (write many word data
into register).
3. Latched CR should be written by RS-485 communication to stay latched. CR will not be latched if written
by MPU through TO/DTO instruction
