Temperature Measurement Module
Instruction Sheet
Warning
9
Please read this instruction sheet carefully before use.
9
Switch off the power before wiring.
9
DVP04PT-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
Use wires with resistance when connect the platinum resistance thermister (RTD) to PLC.
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. DVP04PT-H2 is able to receive 4 points of platinum temperature
sensors (PT100 3-WIRE 100
Ω
3850 PPM/
°
C (DIN 43760 JIS C1604-1989)) and convert them into 14-bit digital
signals. Besides, through FROM/TO instructions in DVP-EH2 MPU program, DVP04PT-H2 is able to read and
write the data in the module. There are 49 16-bit control registers (CR) in DVP04PT-H2.
DVP04PT-H2 displays temperatures in Celsius (resolution: 0.1°C) and Fahrenheit (resolution: 0.18°F).

*1: Wiring for analog input should adopt cables of PT100 temperature sensor or double shielding cable and should be
separated from other power cables that may cause interference. Please use 3 wires for PT100.
*2: Terminal FG is the ground location for noise suppression.
*3: Please connect the
terminal on both the power module and DVP04PT-H2 to the system earth point and ground the
system contact or connect it to the cover of power distribution cabinet.
