Product Overview
The ABB TC501V150 (3BSC550038R3) is a specialized I/O Speedometer Input Module designed for use in high-performance industrial automation and process control systems. It serves as a key interface for acquiring rotational speed signals—typically from tachometers or other rotating machinery sensors—and converting them into digital signals for analysis and control by ABB’s distributed control systems (DCS), such as System 800xA or Advant OCS.
Engineered for high accuracy and reliability, the TC501V150 supports a wide range of signal types and frequencies, making it ideal for real-time monitoring, feedback loops, and motion control systems where speed measurement is critical to maintaining process integrity.
