GE A20B-1001-0550

1. Bus without power supply:
Check if the bus 24V power supply is connected properly
2. Module cannot be brought online:
Check the communication address of the module configuration
3. Communication instability and frequent disconnection:
a. Check whether the grounding of the communication cable shielding layer is normal and reliable;

Description

GE A20B-1001-0550

GE A20B-1001-0550

The software design adopts a modular design approach, including the PWM signal generation program required by the signal source, A/D conversion program, FIR filtering design, DFT algorithm program, RS485 communication program, etc. The system is powered on by first configuring the hardware, initializing RS485, initializing the A/D module, and then generating two PWM signals to output to the signal source generation circuit. Starting the data acquisition program, the A/D conversion data is filtered, and the filtered signal is DFT calculated to calculate the insulation resistance and distributed capacitance of the system. The calculated data is then transmitted to the upper computer. The main program flowchart is shown in Figure 3.

Power plants still have high requirements for valve positioners, and the technical performance requirements are as follows:
1. It should be a modular design, high-precision intelligent valve locator locator;
2. It has the function of power-off and signal protection, which means that the valve has the function of protecting the position when the signal is cut off or powered off without adding other equipment, that is, it stops in its original position. Alternatively, it can be equipped with power off and signal off reset functions, that is, to achieve power off and signal off reset functions without adding other equipment, so as to return the valve to the safe position.
3. Equipped with local automatic calibration and manual calibration, operation function with automatic calibration and manual calibration (without additional equipment), operation function, and can be adjusted using a manual operator (such as 275375691)
4. Its input and output must be 4-20mA current signals
5. Capable of continuous trouble-free operation in an environment of -40…+85 ° C
6. Has the ability to resist strong electromagnetic interference
7. Anti vibration ability: The locator is required to have strong anti vibration ability
8. Waterproof and dustproof capabilities, protection level IP65
