Basic information
Product Model: PCD231B101
Product Number: 3BHE025541R0101
Series: Static Excitation System
Product type: Excitation control module

Electrical parameters
Power supply: 24V DC, 5A
Input and output: Supports multiple signal input and output, can be connected to sensors, actuators and other devices, usually has multiple control channels, and can simultaneously monitor and control multiple power generators.
Communication capability
Optical fiber communication: It can be used for PROFIBUS optical fiber communication networking and supports bus, star and ring network structures. The multimode wavelengths of optical fibers are 850nm and 1310nm, and the single-mode wavelengths are 1310nm and 1550nm. The multimode transmission optical fibers have 50/125, 62.5/125, and 100/140um, while the single-mode ones have 8.3/125, 9/125um, and 10/125um. The transmission distance is 2KM for multimode and 20KM for single-mode. The type of optical fiber interface is ST interface.
Other interfaces: Usually supports multiple communication interfaces, such as Ethernet, serial ports (RS-232, RS-485), Profibus, CAN, etc., to facilitate data exchange with other devices and networks.

Functional characteristics
Excitation control: Specifically designed for the control of electromagnetic excitation equipment, it can adjust the excitation current and voltage of the generator to ensure they are maintained at an appropriate level, meeting the demands of the power system.
Monitoring and protection: It has a protection function and can monitor and protect the generator from overcurrent, overvoltage or other faults. It has both current and voltage monitoring functions, which can monitor the electrical parameters of the generator in real time. It can also detect abnormal situations and generate alarm information to help the operator or control system take appropriate measures.

In addition, the operating temperature range of PCD231B101 is generally from -25 ℃ to + 60℃. It adopts industrial-grade design and features anti-vibration, anti-shock, high-temperature resistance, dust and water resistance, etc., making it suitable for harsh industrial environments.
