The CMA198 is ABB's controller processor module for power semiconductor and power conversion applications.

The CMA198 is modular in design and can be used in a variety of different applications, including diodes, thyristors and thyristors.

Controller processor module is an important part of programmable controller, the main function is to continuously collect input signal, execute user program, refresh system output. It is composed of a microprocessor (CPU chip) and memory, in the programmable controller system, the CPU module is equivalent to the human brain and heart, it constantly collects input signals, executes user programs, and refreshes the output of the system. Memory is used to store programs and data.

CMA198 processor module is an important part of computer, it is composed of processor chip, heat dissipation device, memory bar, hard disk and so on.

The main function of the CMA198 processor module is to process the data in the computer, including arithmetic operations and logic operations, etc. It is composed of the processor chip, heat dissipation device, memory, hard disk, etc. The processor chip is the core of the processor module, which determines the performance and function of the processor.

Silicon Controlled Rectifier, full name Silicon Controlled rectifier, SCR for short, is a high-power electrical component, also known as thyristor. CMA198 It has the advantages of small size, high efficiency and long life. In the automatic control system, it can be used as a high-power driving device to realize the control of high-power equipment with low-power control. It has been widely used in AC and DC motor speed control system, power regulation system and servo system.

Thyristors are divided into two kinds: unidirectional thyristors and bidirectional thyristors. CMA198 bidirectional thyristor is also called TRIAC. The bidirectional thyristor is structurally equivalent to two unidirectional thyristors in reverse connection, and this thyristor has a dual pilot pass function. Its on-off state is determined by the control pole G. Adding a positive pulse (or negative pulse) to the control pole G can make it forward (or reverse) conduction. The advantage of this device is that the control circuit is simple and there is no reverse voltage problem, so it is particularly suitable for AC contactless switch use.
