DVP04TC-S Thermocouple Sensors
Instruction Sheet
1 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.
2 INTRODUCTION
2.1 Model 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.
