S-123H 3BHB030479R0512 | ABB Keyphase module

ABB S-123H 3BHB030479R0512 Keyphasor Module, with its input and output interfaces

· Input voltage: 24V DC, providing stable power support for the normal operation of the module, ensuring the normal operation of internal circuits and signal processing.

· Keyphase signal input: Receive keyphase sensor signals from rotating machinery, usually pulse signals, with input amplitudes generally between 0-24V, used to measure 

parameters such as rotational speed, phase, and rotor position of rotating machinery, in order to achieve precise monitoring and control of rotating machinery.

· Accept reference signals from external sources, such as synchronization signals, clock signals, etc. The signal type is generally a digital signal, such as 0-5V, 0-10V DC voltage 

signals or 4-20mA DC current signals, used for comparison and calibration with key signals to improve measurement accuracy and stability.

· After processing, the key phase pulse signal is output to external devices. The output signal is usually an adjustable voltage or current signal, and its range and accuracy 

depend on specific control requirements. It can be used to trigger synchronous operations of other devices, such as oscilloscope triggering and data acquisition synchronization.

· Output the working status signals of the module to external systems, such as normal operation, fault alarm signals, etc. The output signals are generally digital signals, such 

as high-level or low-level signals, which can be used to trigger external alarm devices or interlock control with other equipment.

· Equipped with serial communication interfaces such as RS232, RS485, or RS422, it is used for data communication with upper computers, PLCs, or other monitoring devices 

to achieve remote monitoring, parameter setting, and fault diagnosis functions. The communication baud rate can generally be set within a wide range, such as 9600bps, 

19200bps, 38400bps, etc.

· It has an Ethernet interface and supports communication protocols such as TCP/IP and Modbus TCP, facilitating high-speed and stable data communication with other devices 

in industrial Ethernet networks. It can achieve functions such as remote monitoring, remote control, and system integration.
