Intelligent self-tuning PID regulator (A series)

This instrument has the following characteristics:

1. A variety of signal inputs: can be arbitrarily selected on site as needed: B, S, K, E, T, J, R, Wre3-25 thermocouple;

PT100, PT100.1, Cu50, Cu100 thermal resistance; type Ⅱ, type Ⅲ linear current and voltage; remote pressure transmitter and

Millivolt signal input. To

2. Multiple output types:

1) Single-phase/three-phase 5A SCR zero-crossing trigger output, which can directly drive 500W load or 600V/100A SCR with time

Proportional (PWM) control, the output cycle is adjustable from 1 to 250 seconds.

2) Single-phase/three-phase 10A solid state relay control output, the output cycle is adjustable from 1 to 250 seconds.

3) Relay control output, contact capacity 220V/10A (resistive load), output cycle adjustable from 1 to 250 seconds

4) Analog signal control output, optional (4～20) mA, 0～10mA or (1～5) V (corresponding to OUT value)

5) Analog signal transmission output, optional (4～20)mA, 0～10mA or (1～5)V (corresponding to the measured value)

6) Relay alarm output, with absolute value upper and lower limit alarm, upper and lower deviation alarm, internal and external deviation alarm and other forms for selection,

The contact capacity is 220V/5A (resistive load).

7) With RS485 or RS232 communication interface, the RS485 interface can connect up to 128 units, and the maximum communication distance can reach 1200 meters.

3. It has two control modes: positive (refrigeration) and negative (heating).

4. You can choose whether you need automatic cold junction compensation for thermocouples.

5. With 2 optional overshoot suppression functions.

6. There are two PID parameter auto-tuning methods, standard/special.

7. Use high-brightness digital tube display or LCD display.

1) Use EEPROM to protect data, the longest protection time can reach 100 years.

2) Adopting measures such as adjustable digital filtering and anti-pulse interference filtering, the anti-serial mode interference performance is better.

3) Adopting switching power supply and watchdog circuit can effectively prevent the influence of grid voltage fluctuation and strong current interference.

8. The input, output and communication circuits are separated from each other.

9. Fault alarm function: the instrument will alarm if the A/D converter is damaged, the memory is damaged, the signal is broken (open circuit), etc.
