3. Overview of Core Competencies

In addition to the basic switch/PID temperature control, it integrates advanced functions such as cold and hot dual PID, phase angle thyristor voltage regulation, non slip line valve position motor control, segmented program temperature rise, multi-channel alarm, automatic setting, remote setting, serial communication, etc.

Core functional features

#1. Parameter graded encryption management

Two level parameter configuration permissions, combined with a 4-digit password lock, can hide key parameters to prevent accidental modifications and unauthorized operations.

#2. Rich control algorithms (core control capabilities)

1.Basic control : ON/OFF two position, standard single path PID;

2.Dual PID for heating and cooling: Two independent sets of PID parameters for heating and cooling, suitable for integrated temperature control equipment for heating and cooling;

3. Controllable silicon phase angle adjustment(single-phase/three-phase): adjust the conduction angle every half wave/120 °, high-precision power adjustment;

4. Zero crossing conduction regulation (single-phase/three-phase): Trigger SCR only at voltage zero point to reduce electromagnetic interference;

5.Non slip feedback electric valve control: relying on time proportional control of actuator switches, eliminating the need for worn slip line potentiometers, reducing maintenance, and eliminating the need for calibration.

#3. Human computer interface (DC1030/DC1040 high-end)

-Dual 4-digit digital tube: real-time measurement value PV on the upper screen, set value SP on the lower screen;

-10 segments of LED light column display output percentage;

-Multi state indicator lights: OUT1/OUT2 output, automatic setting AT, three-way alarm AL1/AL2/AL3, manual MAN, program running PRO flashing indicator.

#4. Segmented program temperature control

Built in 2 independent programs, each with up to 8 segments; Two sets can be combined in series to form 16 complete temperature ranges, supporting automatic operation of heating, insulation, and cooling timing.

#5. alarm system

A single controller supports 3 independent alarm outputs, with 17 configurable alarm modes built-in, including timed alarm function.

#6. Auto tuning

One click self-tuning of PID parameters, quickly matching different heating/cooling loads, simplifying debugging.

#7. Remote setting function

The second analog input (4~20mA/0~5V, etc.) is connected to an external signal, and the temperature setting value SP is remotely set with a sampling period of 500ms.

#8. Manual/automatic undisturbed switching

It can be freely switched between automatic PID control and manual output mode.

#9. Serial communication (optional)

Supports RS232/RS485 ASCII protocol, with a maximum of 30 DC1000s mounted on a single host; The upper computer can read PV measured values, output status, modify set values, and remotely modify all device parameters.

Supplementary Principles of Control Algorithms

1. * * Phase angle control * *: By changing the SCR conduction time during the AC half cycle, the output power can be continuously adjusted with extremely high temperature control accuracy; Divided into single-phase and three-phase (adjustable every 120 °);

2. * * Zero crossing control * *: Trigger the thyristor only at the zero point of the AC voltage to reduce harmonic interference, suitable for equipment with high requirements for electromagnetic environment;

3. * * Non slip line valve control * *: By controlling the proportional positioning of the output duration of opening and closing the valve, there is no need to feedback the potentiometer, avoiding potentiometer wear and poor contact faults.
