Product Description
The AAP135-S50/K4A00 is a high-precision pulse input module engineered by Yokogawa for Field I/O (FIO) integration. It is designed to process pulse count signals ranging from 0 to 10 kHz, making it suitable for interfacing with flow meters, speed sensors, and other frequency-based industrial instrumentation. The module provides 8 fully isolated input channels, ensuring strong noise immunity and maintaining signal integrity in electrically noisy industrial environments.
The AAP135-S50 is a standard non-explosion-proof variant, making it suitable for installation in safe-zone control cabinets. The /K4A00 option includes the ATK4A-00 interface adapter, which simplifies field wiring connections to the module backplane. Its compact and lightweight design allows efficient high-density installation within Yokogawa DCS and PLC control systems.
