Thank you for choosing DELTA DVP PLC Series. DVP08TC-H2 is able to receive 8
points 0~150mV voltage input of thermocouple temperature sensors (J-type, K-type,
R-type, S-type, T-type, E-type, N-type) and convert them into 24-bit digital signals.
Besides, through FROM/TO instructions in DVP-EH2 MPU program, the data in
DVP08TC-H2 can be read or written. There are 49 16-bit control registers (CR) in it.
DVP08TC-H2 displays temperatures in Celsius (resolution: 0.1°C) and Fahrenheit
(resolution: 0.1°F).
a This Instruction Sheet only provides descriptions for electrical specifications, general
specifications, installation & wiring. Other detail infromation about programming and
intructions, please see “DVP-PLC Application Manual: Programming”. For more
information about the optional peripherals, please see individual product instuction
sheet or “DVP-PLC Application Manual: Special I/O Modules”.
a DVP08TC-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.
a Do NOT connect the AC main circuit power supply to any of the input/output terminals,
or it may damage the PLC. Check all the wiring prior to power up. To prevent any
electromagnetic noise, make sure the PLC is properly grounded . Do NOT touch
terminals when power on.
a Keep the wire as short as possible between thermocouple and PLC and the power
wire as far away as possible from I/O wire to prevent interference.
a When setting the thermocouple temperature sensor mode, please make sure that the
settings of CR#2~ CR#9 are correct, or it will cause serious errors.

*1: The wiring used for analog input should adopt the connection cable or shielding cable of
thermocouple temperature sensor J-type / K-type / R-type / S-type / T-type / E-type / N-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: Please connect the
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.
