Overview
The Yokogawa NFDV561-P51 is a 64-channel digital output module in the NFDV561 series, designed for high-performance industrial automation systems. It delivers isolated 24 V DC output for reliable control and supports multiple fallback options to maintain safe operation during system events.
Key Features
- Provides 64 digital output channels with 24 V DC voltage and 100 mA load per channel.
- Supports HOLD, OFF, or NO fallback actions to configure outputs consistently.
- Compact and lightweight design (0.3 kg) ensures easy installation and handling.
- Features MIL connector cable for secure and efficient external connections.
- Responds quickly with ≤3 ms status output response time.
- Operates with field power supply range of 20.4–26.4 V DC.
