Accessory. These devices are microprocessor-based temperature regulating controllers which may be provide with
normally closed and/or open contacts. They are intended for installation completely within an overall panel or Process
control Enclosure and are used in heating or cooling applications. Please Install within a separate UL Listed enclosure
only, keep the enclosure away from airbome dust or high humidity and prevent electric shock or sudden shock. Also, it
is equipped with protective methods such as some special tool or key to open the enclosure, so as to avoid the hazard
to users or any damage to the module.
WARNING!
Prevent dust or metallic debris from falling into the controller that will cause malfunction.

Note 2: Factory setting: PT100 input. It is adjustable for linear input and feedback ranges. The default range of input feedback is -999 ~ 9,999. For
example, when a 0 ~ 20mA analog input is selected as the input temperature sensor type, -999 indicates 0mA and 9,999 indicates 20mA. If
change the input range to 0 ~ 2,000, then 0 indicates 0mA and 2,000 indicates 20mA. One display scale is equal to 0.01mA.
Output Function
Output control for DTC is selective: Control output (heating, cooling), Alarm output, or Retransmission output.
Control Output:
Temperature can individually be controlled by two groups of outputs: cooling (forward) or heating (reverse). When Dual
Loop output control is used, two output controls shall be designed for cooling (forward) or heating (reverse). If two
control outputs with the same direction are performed, only 1
control, ON/OFF control, Manual control, and PID program control.

Description of Function and Parameters Setting:
PID program control by 8 patterns (Pattern No. 0~7) is supported in DTB series. Each pattern contains 8 steps (step
No. 0 ~ 7), one Link Pattern parameter, one Cycle parameter and one Actual Step parameter.
Start Pattern: is in operation mode and it is used to set the Start Pattern of PID program control (This
parameter appear in mode only).
Steps: Include set point X and execution time T, these two parameters setting. The set point (SV) should reach
temperature X after the period of execution time T. If the set point is the same as the result of the previous setting,
then it is called Soak program control. If not, then it is called Ramp program control. Therefore, PID program control is
also called Ramp/Soak program control.

The default of step No. 0 in this controller is Soak program control. The controller will control the temperature (PV) to

provided by step No. 0.

F) Cycle Parameter: Additional execution cycle number. For example, when set
4 should execute twice in addition. Including the origin one time execution, the pattern executes totally three times.

Actual Step Parameter: Execution step number per pattern (can set to 0 ~ 7). For example, when set

indicates that pattern No 7 will not execute other steps than step 0 to step2.

Execution: When is set to , the program will start to execute in order from the step 0 of start pattern.
When is set to , the program will stop and the control output is disabled.
When is set to , the program will stop and the temperature at that time will be controlled at the set point
before program stop. Select again, then the program will restart and execute from step 0 of start pattern.
When is set to , the program will hold and the temperature at that time will be controlled at the set point
before program hold. Select again, then the program will follow the step before hold and start to execute
through the rest of the time.
Retransmission Output:
st
When the 1 group output of this controller is linear voltage or current output, it can be Retransmission that is the output
variation corresponding with input. For example, when read value = 0 with input range 0 ~ 1,000, output will be 0mA or
0V. When read value = 1,000, output will be 20mA or 10V.
