Engineered to address the most demanding signal acquisition challenges in Oil & Gas, Power Generation, and Chemical Processing, this module integrates seamlessly into Yokogawa CENTUM VP and ProSafe-RS control platforms. Whether you are replacing an end-of-life component or expanding an existing control loop, sourcing an Original New NFAP135-S01 ensures full compatibility and uncompromised system integrity.

We stock verified Original New units ready for immediate dispatch. Contact our team for a competitive quote and fast lead time confirmation.

Typical Application Scenarios

✅ Oil & Gas — Flow Totalization: Interfaces with turbine and vortex flow meters across wellhead and pipeline SCADA systems. Eliminates signal noise through channel-to-channel isolation, ensuring accurate custody transfer measurements in high-EMI environments.

✅ Power Plants — Utility Metering: Captures pulse outputs from electricity, steam, and water meters for real-time energy balance calculations. Supports plant-wide energy management programs with millisecond-level pulse resolution.

✅ Chemical Processing — Batch Control: Counts dosing pump strokes and reactor cycles within Yokogawa CENTUM VP batch sequences. The module’s robust isolation architecture prevents cross-channel interference during simultaneous multi-stream operations.

✅ Water & Wastewater Treatment — Flow Monitoring: Integrates with electromagnetic and ultrasonic flow transmitters to provide totalizing data for regulatory compliance reporting and pump efficiency analysis.

✅ Manufacturing — Production Counting: Reliably captures high-speed pulse signals from conveyor encoders and packaging line sensors, supporting OEE (Overall Equipment Effectiveness) tracking within Control Module networks.

Core Features & Technical Advantages

• 8 Isolated Pulse Input Channels — Channel-to-channel and channel-to-system electrical isolation eliminates ground loops and protects signal integrity across all inputs simultaneously.
• Multi-Signal Compatibility — Accepts contact closure, voltage pulse (5-30 VDC), and current pulse inputs without hardware reconfiguration, reducing Spare Parts inventory complexity.
• High-Frequency Pulse Capture — Supports pulse frequencies up to 10 kHz per channel, enabling precision measurement of high-speed industrial processes.
• Heavy-duty Industrial Construction — Conformal coating and robust housing protect against humidity, vibration, and corrosive atmospheres common in Oil & Gas and Chemical Processing facilities.
• Hot-Swap Capability — Designed for live insertion and removal within Yokogawa I/O subsystems, minimizing planned and unplanned downtime during maintenance windows.
• Native DCS Integration — Plug-and-play compatibility with Yokogawa CENTUM VP, ProSafe-RS SIS, and STARDOM SCADA platforms within existing PLC System and DCS architectures.
• Diagnostic LED Indicators — Per-channel status LEDs provide instant visual confirmation of signal presence and module health without requiring software tools.

Technical Specifications & Selection Guide

Selection Tip: If your application requires analog signal acquisition alongside pulse counting, consider pairing the NFAP135-S01 with Yokogawa analog input modules (e.g., AAI143 series) for a complete mixed-signal I/O solution within the same DCS chassis.
