Safety Instrumented System, abbreviated as SIS; also known as Safety Interlocking System. It mainly constitutes the alarm and interlock parts in factory control systems. It triggers alarm actions, adjusts or stops the control based on the detection results in the control system, and is an important component in the automatic control of factory enterprises.…
In the monitoring of industrial equipment operation, the phase comparator module is one of the key components. Its core function is to capture the phase signals of rotating machinery, providing a reference for vibration analysis, speed measurement, etc. The improved 3500/25 phase comparator module launched by Bently in the United States belongs to the…
Program interface The program interface is a service invocation mechanism provided by the operating system for programmers. It enables the interaction between user programs and the kernel through system calls, covering functions such as process control, file operations, and process communication. As the sole legal entry point for applications to access system resources, it triggers…

The power source that supplies the excitation current to the synchronous generator and its associated equipment is collectively referred to as the excitation system. It generally consists of two main components: the excitation power unit and the excitation regulator. The excitation power unit supplies the excitation current to the rotor of the synchronous generator; while…
The central processing module (CPM) is composed of the secondary power supply board (PWS), the alarm processing board (ALM), the main processing board (AMP), the central database board (CDP), the bus control board (BCP), and the built-in business processing board (ISP). The call connection management of the entire switching system is carried out by the…
The proportional controller is a control device that performs linear regulation based on the deviation signal. Its control law is that the input deviation is proportional to the output quantity, and it has the characteristics of fast response but with static deviation. When the system is stable, the controller output is zero, but the actual…
