The TBU810 is a powerful closed-loop control/valve positioner for a wide range of industrial process control applications. It can precisely control the opening of the valve to achieve the purpose of adjusting process variables.
Main functions of the TBU810
Closed-loop control: According to the deviation between the set value and the actual measured value, the valve opening is automatically adjusted to achieve stable control of process variables.
Valve positioning: Accurately position the valve to ensure that the valve opening is proportional to the control signal.
PID control: PID control algorithm is used to achieve fast and stable control effect.
Self-tuning: Parameters can be automatically adjusted to simplify the debugging process.
Fault diagnosis: With fault diagnosis function, can be found in time and alarm.
Multiple input and output: Support a variety of input and output signals, such as 4-20mA, 0-10V, etc.
HART protocol: Support HART protocol, easy to communicate with the host computer.
Working principle of the TBU810
The TBU810 calculates the deviation by receiving the signal from the process variable sensor and comparing it with the set value. Then, according to the PID control algorithm, a control signal is output to drive the actuator (valve) for adjustment, thereby reducing the deviation and making the process variable stable near the set value.
