Performance characteristics
Measurement channel: A three channel measurement system based on a microcontroller, which can achieve high-precision speed measurement and analysis.
Security protection: SIL3 certification is achieved, and each monitor is password protected, with a high level of security; Each channel can set up to 6 limit values, which can effectively provide overspeed protection.
Output function: Each channel has two current outputs with scaling and dual current functions, one of which is electrically isolated; There are two 24VDC relay outputs that can be used to trigger alarms or shut down operations.
Signal processing: Channels can compare pulses and output signals with each other to ensure measurement accuracy and reliability.
Power system: Provides redundant power supply for the monitor and backplane to improve system stability.
Self checking function: It has the self checking function of electronic circuits and sensors, which can simplify fault detection and display messages in plain text.
Communication interface: Equipped with RS232 interface for parameter input, RS485 interface for data exchange with the upper computer, and optional Profibus DP interface.
Electrical isolation: Binary input and output signals are electrically isolated to enhance the system's anti-interference ability.
Hot swappable function: supports hot swappable cards during operation, making maintenance and upgrades convenient.
Measurement Function 
Independent channel: Two channels can be used independently to measure the speed, zero speed, key phase pulse signal, etc. of two shafts.
Combination channel: Two channels can also be used in combination to monitor the rotation direction of one axis, the speed difference between two axes, or as part of a multi-channel/redundant system.

application area 
Power industry: used for speed monitoring and overspeed protection of power generation equipment such as steam turbines and gas turbines, ensuring the safe and stable operation of generator sets.
Petrochemical industry: In rotating equipment such as compressors and pumps, monitor the speed and prevent overspeed to ensure the reliability of the production process.
Paper industry: used for pulp mills, paper machines and other equipment to ensure that the equipment operates within the specified speed range, improve product quality and equipment life.
In the mining industry, it can be applied to equipment such as mine hoists and crushers to prevent safety accidents and equipment damage caused by overspeed.
