Instruction Sheet

Warning

9Please read this instruction sheet carefully before use.

9Switch off the power before wiring.

9DVP04TC-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.

9DO 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.

9DO NOT touch any terminal when the power is switched on.

9Make sure the ground termnial is correctly grounded in order to prevent electromagnetic interference.

9Keep 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).
