Overview
The Yokogawa NFDV551-P11 is a 32-channel digital output module designed for industrial automation systems. It outputs transistor contact signals and delivers reliable performance under demanding conditions. The module supports flexible power supply ranges, fast response times, and robust isolation for system integrity.
Key Features
- Operates at a rated applied voltage of 24 V DC for industrial control applications.
- Each channel supports up to 100 mA load current at 26.4 V DC.
- Field power supply voltage range spans 20.4–26.4 V DC.
- Current sink output ensures efficient and precise signal transfer.
- Minimal leakage current (<0.1 mA) when output is OFF.
- Fast status response time of 3 ms or less.
- Supports configurable fallback actions: HOLD, OFF, or NO.
- Compact design weighing 0.2 kg, suitable for easy installation.
- Compatible with pressure clamp terminals and MIL connector cables.
