Instruction Sheet
Warning
Please read this instruction sheet carefully before use.
Switch off the power before wiring.
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.
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.
Use wires with resistance when connect the platinum resistance thermister (RTD) to PLC.
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 100Ω 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).

power module
*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
system contact or connect it to the cover of power distribution cabinet.
Note: DO NOT wire empty terminal

1. b0 is reserved.
2. b1 is reserved.
3. When b2 is set as 1, all the settings will return to default settings.
ERR LED definition: default of b12 ~ b15 = 1111
1. b12 corresponds to CH1. When b12 = 1 or the scale exceeds the range,
ERR LED will flash.
2. b13 corresponds to CH2. When b13 = 1 or the scale exceeds the range,
ERR LED will flash.
