Official Full Product Name & Function Description Full Official Name: ABB PFVI401 Pulse & Frequency Input Module, Article No. 3BSE018732R1 Product Series: ABB Advant OCS / S400 I/O System (compatible with System 800xA Industrial IT DCS) Core Function: High-speed 4-channel pulse/frequency/counter input module for industrial distributed control systems. It captures high-frequency pulse signals from incremental encoders, turbine flow meters, tachometer speed sensors, and pulse-output energy meters, converts raw pulse signals into digital flow, speed, position, and frequency data for the DCS controller. Built-in optoelectronic isolation eliminates field-side electromagnetic interference, delivering high-precision real-time measurement unavailable from standard digital input modules with slow s
