Temperature Measurement Module
Instruction Sheet
Warning
9 Please read this instruction sheet carefully before use.
9 Switch off the power before wiring.
9 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.
9 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.
9 DO NOT touch any terminal when the power is switched on.
9 Make sure the ground termnial
is correctly grounded in order to prevent electromagnetic interference.
9 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.
Introduction
1.1 Model Explanation & Peripherals
Thank you for choosing Delta’s DVP series. 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, DVP04TC-H2 is able to read and write the
data in the module. There are 49 16-bit control registers (CR) in DVP04TC-H2.
The power unit and module of DVP04TC-H2 are separate, compact in size and easy to install.
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 or K-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
.
Note: Use 60/75°C copper conductor only.
