Product Description
The AAP135-S50 is a high-precision pulse input module for Yokogawa Electric Corporation’s FIO (Field network I/O) system, commonly deployed in CENTUM VP and CS 3000 control systems. It converts pulse train signals from devices such as flowmeters, power meters, and tachometers into engineering units for flow rate, totalized volume, or rotational speed monitoring.
The "S50" suffix indicates a conformal coating for ISA G3 environmental protection, providing resistance to corrosive gases and humidity for long-term reliability in chemical, power, and process industries.

Application and Integration
The AAP135-S50 is installed in FIO node units (ANB series) and communicates with the Field Control Unit (FCU). It is ideal for high-precision flow totalization and rotating equipment speed monitoring. The module supports hot-swapping, allowing maintenance or replacement without interrupting process control.
Professional FAQ
Can the AAP135-S50 power a field sensor?
No. External 12 V or 24 V DC power is required to drive the field sensors or open-collector outputs.
What is the difference between frequency measurement and totalization?
The module simultaneously measures instantaneous frequency (for flow rate) and increments a 32-bit internal counter (for accumulated volume).
Is this module suitable for high-speed motion control?
No. With a 10 kHz limit, it is optimized for process instrumentation. High-speed servo feedback applications require specialized FA-M3 high-speed counter modules.
