CPU上集成的两个Modbus通讯接口和可选集成的以太网或ARCNET网络接口外，通过通讯扩展接口还能扩展如Profibus DP、DeviceNet、CANopen和以太网等总线接口。

The CMA120 3DDE300400 is an excitation system or power amplifier product commonly used to control the excitation current of a motor generator.

Here are some of the parameters and features of the CMA120 3DDE300400:

Application field:

Electric power plant: used to control the excitation current of the generator to adjust the voltage output to ensure the stability and quality of the power supply.

Power transmission and distribution: used to adjust the output voltage of the generator to match the load demand and maintain the stability of the power network.

Integrated gate commutator thyristor (IGCT) : An IGCT is a press-mounted device that uses a moderately high press-mounted technology so that the transistor is 

press-mounted together with a heat sink for the electrical connection of the power terminal.

The control power consumption of IGCT is usually 20 ~ 50W, and its switching frequency is usually in the range of 500Hz.

Communication module: The CPU also supports up to 4 communication expansion interface modules, which can be extended to any standard bus protocol module.

In addition to the two Modbus communication interfaces integrated on the CPU and the optional Ethernet or ARCNET network interface, the communication extension 

interface can also be extended such as Profibus DP, DeviceNet, CANopen and Ethernet bus interfaces.
