	WARNING

Always read this instruction thoroughly before using the DVP04TC-S.

Make sure that power is OFF before wiring.

This is an OPEN TYPE PLC. The PLC should be kept in an enclosure away from airborne dust, humidity, electric shock risk and vibration. Also, it is equipped with protective methods such as some special tools or keys to open the enclosure, in order to prevent hazard to users or damage the PLC.

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.

Do NOT touch internal circuit within 1 minute after power is OFF.

Make sure that the DVP04TC-S is properly grounded , to avoid any electromagnetic noise.

INTRODUCTION

2.1Model Explanation and Peripherals

Thank you for choosing DELTA’s DVP Series PLC. The DVP04TC-S allows the connection of four thermocouple sensors (Type J/K). The DVP04TC-S series can read/write the data by using instructions FROM / TO via DVP-PLC SS/SA/SX/SC MPU program. There are 49 CR (Control Register) in each module and 16 bits for each register.

DVP04TC-S thermocouple sensor can update software version by RS-485. Power supply and main processing units are sold separately.

The DVP04TC-S works with both Centigrade and Fahrenheit. The input resolution for Centigrade is 0.1 degrees and for Fahrenheit is 0.18 degrees.
