The Yokogawa NFDV561-P00 S2 is a high-density 64-channel Digital Output Module for CENTUM VP systems. Featuring a 24VDC current sink design and 100mA capacity per channel, this module offers reliable, high-precision control for valves, relays, and indicators in demanding industrial settings.
The Yokogawa NFDV561-P00 S2 functions as a high-density Digital Output Module designed for the CENTUM VP distributed control system (DCS). This module provides 64 discrete output channels, allowing engineers to control a vast array of field devices from a single slot. It operates using a current sink output format, which significantly improves noise immunity and ensures stable switching in high-interference industrial environments.
To maintain system integrity, the NFDV561-P00 S2 utilizes a 24V DC field power supply with a generous operating range of 20.4 to 26.4V DC. Each of the 64 channels supports a 100mA load, making it ideal for driving interposing relays, solenoid valves, and indicator lamps. The module limits the output ON voltage to a maximum of 2V DC and keeps leakage current below 0.1mA in the OFF state, preventing “ghost” signals and ensuring that connected devices de-energize reliably.
The compact physical profile of the NFDV561-P00 S2 (3.2cm width) allows plant operators to maximize cabinet density. It integrates seamlessly into the Yokogawa FIO (Field network I/O) bus, providing the controller with real-time status updates for every channel. This high-channel count reduces the overall hardware footprint and simplifies the wiring architecture for complex process plants and power generation facilities.
Engineers deploy the NFDV561-P00 S2 in large-scale automation projects that require high-density discrete control, such as:
