NFAP135-S00 | Yokogawa | 8-Ch Pulse Input Module 24V DC

Product Description

High-Speed Pulse Data Acquisition

The Yokogawa NFAP135-S00 (Model NFAP135) is a precision Pulse Input Module specifically designed for the Yokogawa STARDOM network-based control system. Unlike standard analog units, this module is engineered to handle high-frequency pulse trains from field instrumentation such as flowmeters, motor encoders, and speed sensors. It provides a reliable interface for converting physical frequency signals into digital data for process totalization and rate monitoring.

Robust Channel Isolation and Performance

The NFAP135-S00 features 8 independent channels with full galvanic isolation, ensuring that electrical noise or ground loops from one field device do not interfere with the system backplane or other input channels. This module supports a wide frequency range from 0 to 10 kHz and is compatible with both 12 V DC and 24 V DC signal levels. Its design is optimized for mission-critical applications in oil & gas and power generation, where deterministic pulse counting is essential for accurate custody transfer and machine health monitoring.
