The AKT91122021 is a type of controller designed for use in various types of applications. It is mainly used for temperature control or process control. For temperature control, the AKT91122021 uses a thermistor to measure the temperature, and then adjusts the output power, heater current or voltage within a certain range to control the temperature to the programmed value. It can also be used for process control, such as liquid level control. It reads out the process value from a liquid crystal display (LCD), and adjusts the current or voltage output to the programmed value.

The AKT91122021 has a wide input range, from 0-20mA or 0-10V DC. It also has a wide output range, from 0-20mA or 0-10V DC. It is equipped with a 10-bit, 1200 pulses/rev pulse width modulation (PWM) output, which is used to control motor speed and other actuators. The PWM output can be further used to drive a dedicated motor-speed-monitoring port.

The AKT91122021 has a comprehensive display with seven LED indicators. It is equipped with a process indicator and a temperature indicator to provide real-time process and temperature feedback. It also features a timing output function, which allows the user to control the timing of the process cycle or temperature cycle.

The AKT91122021 can be used for various applications, including temperature control and process control. For temperature control, it can be used to control the temperature of ovens, chambers, reactors, and other process systems. For process control, it can be used to control liquid levels, valve positions, and other process variables. It can also be used for motor speed control.

The working principle of the AKT91122021 is simple. It is a closed loop control system, in which the process or temperature is perceived and then compared to the preset value. Based on this comparison, the controller will adjust the output, either in current or voltage to the programmed value. The output is then fed back to the process or temperature, which is then adjusted according to the feedback. The controller will then continue to cycle in this fashion, making adjustments as necessary to keep the process or temperature at the programmed value.

In conclusion, the AKT91122021 is a versatile controller with a wide range of applications such as temperature control and process control. It is equipped with a comprehensive display and several automated features, which make it suitable for use in both industrial and commercial environments. Its simple working principle allows it to maintain accurate control of the process or temperature, ensuring that the system is working as intended.
