Core functions

（1） Signal Processing and Conversion

Referring to the functions of modules in the same series, this unit module may undertake signal processing and conversion tasks. In the power system, high amplitude and high voltage signals output by voltage transformers (VT) and current transformers (CT) can be converted into standard signal levels suitable for protection functions and monitoring system processing. Just as the RLHC100 transformer unit module converts VT and CT inputs into appropriate signals, this module can also adjust the original signals to the appropriate range, providing support for accurate analysis and processing of data by backend devices and ensuring stable operation of power equipment.

（2） Communication and Data Interaction

Given the high dependence of industrial automation systems on communication and interaction between devices, RK682011-BA RL0B 100 is highly likely to have communication capabilities. May serve as a communication node for data transmission with other devices or systems, enabling information sharing and collaborative work. Analogous to the RLSC100 human-machine communication bus module as a central point connecting various devices in a star shaped network, this module may play a role in data transfer and coordinated communication in industrial networks, ensuring smooth data flow between different components in the control system and assisting in the efficient operation of automation systems.

（3） Control and protection functions

In industrial environments, stable operation and safety protection of equipment are crucial. This standard unit module may integrate control and protection algorithms, which can monitor system parameters in real time. Once abnormal situations such as overcurrent, overvoltage, and frequency anomalies are detected, the protection mechanism is quickly triggered, and measures such as cutting off the circuit and issuing alarms are taken to avoid equipment damage and ensure the safety and continuity of industrial production processes. Similar frequency/flux unit modules (such as RLOF100) monitor and control frequency and flux related parameters, and this module may also control specific parameters to maintain system stability.

Working principle

Although there is currently no official information on the working principle of this module, it is speculated that its signal processing and conversion functions may be based on analog-to-digital conversion circuits and signal conditioning chips. Through these circuits and chips, the input high amplitude and high voltage signals are processed by voltage reduction, filtering, analog-to-digital conversion, etc., and converted into digital signals for subsequent circuit analysis. In terms of communication, standard communication protocols such as Modbus, Profinet, etc. may be used to establish connections with external devices through internal communication controllers and achieve data transmission and reception. The control and protection functions or rely on the built-in microprocessor, which runs pre written control and protection algorithms, analyzes the collected signals in real time, and once an abnormality is determined, outputs corresponding action signals through the control circuit to perform protection operations.
