WARNING
Always read this manual thoroughly before using the DVP04TC-S.
In order to avoid electric shock, do not touch the terminals or conduct any maintenance while power is
applied to the PLC. Never open the PLC. Only qualified Delta personell should conduct any internal
electrical work on the PLC.
This is an OPEN-TYPE device and must be placed in an environment away from high temperatures, high
humidity, exceessive vibration, corrosive gases, liquids, airborne dust, and metallic particles when installed
in an enclosure.
Do not apply AC power to any of the input/output terminals, this will cause permanent damage to the
DVP04TC-S.
Do NOT touch terminals when power on.
Make sure that the DVP-04TC is properly grounded
, to avoid any electromagnetic noise.

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.R.S.T).
The DVP04TC-S series can read/write the data by using commands
FROM / TO via DVP-PLC SS/SA/SX/SC MPU program. There are 49 CR (Control Register) in each module
and 16 bits per 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.

Note 1: Use only the wires that are supplied with your thermocouple sensor. Tighten PLC terminal screws to a
torque of 1.95 kg-cm (1.7 in-lbs).
Note 2: Terminal SLD is a grounding location for noise suppression.
Note 3: Please connect
terminal of power supply module and
terminal of DVP04TC-S thermocouple
sensors module to system earth ground.
Warning: DO NOT connect wires to the No Connection (
) terminals. Use copper conductor only, 60/75
℃

series to an MPU.
Connection to a DVP-PLC MPU in
series
When DVP04-TC modules are connected to an MPU, the modules are
numbered from 0 – 7. 0 is the closest to the MPU and 7 is the furthest.
The Maximum number of modules is 8 modules and they do not occupy
any digital I/O points of the MPU.
