Yokogawa NFDV561-P00 S2 64-Channel 24V DC Digital Output Module

Product Overview

The Yokogawa NFDV561-P00 S2 is an ultra-high-density digital output module engineered for the CENTUM VP Distributed Control System (DCS). Featuring 64 discrete output channels, this module is designed to command a vast array of binary field devices from a single I/O slot. It utilizes a current sink output configuration, providing superior noise immunity and stable switching performance for 24V DC loads. The NFDV561-P00 S2 is a primary choice for facilities requiring massive discrete control capabilities within a compact hardware footprint, ensuring deterministic execution of logic for large-scale industrial processes.

Technical Characteristics

The NFDV561-P00 S2 is defined by its efficiency, signal purity, and high-density architecture:

High-Density Control Architecture With 64 isolated channels, this module significantly reduces the number of I/O units required in a control cabinet. This helps minimize hardware costs and simplifies cable management for complex systems involving numerous solenoid valves, relays, and indicators.

Precision Switching Performance The module is optimized for 24V DC operations with a load capacity of 100mA per channel. It maintains exceptional signal integrity with an ON-state maximum voltage drop of only 2V DC and a negligible OFF-state leakage current of less than 0.1mA. This precision prevents "ghost" signals and ensures that field actuators respond exactly to controller logic.

Current Sink Configuration By employing a current sink (NPN) output format, the module offers enhanced protection against electromagnetic interference (EMI) typical in heavy industrial environments. This configuration is widely used for interfacing with PLC inputs, interposing relays, and electronic actuators that require a common positive supply.

Robust Operational Range Designed for the rigors of 24/7 industrial production, the module supports a wide field power supply range of 20.4 to 26.4V DC. Its rugged mechanical design and high-quality Japanese engineering ensure long-term stability in power generation and chemical processing facilities.
