It provides 24 V DC transistor outputs in a current-sink configuration for switching external field loads. The module supports individual ON\/OFF output control and configurable output fallback behavior, with an external field power supply required for output operation.\u003c\/p\u003e\n\u003ch3\u003eFunctional Description\u003c\/h3\u003e\n\u003cp\u003eThe NFDV561-P50 converts digital control commands from the FCN\/FCJ controller into discrete electrical output signals. Its 64 output channels can control compatible DC field loads within the specified voltage and current limits.\u003c\/p\u003e\n\u003cp\u003eThe current-sink output arrangement switches the load current toward the common negative supply. Field devices must therefore be wired with the correct polarity and an appropriate external 24 V DC supply.\u003c\/p\u003e\n\u003ch3\u003eOutput Characteristics\u003c\/h3\u003e\n\u003cp\u003eThe module provides isolated 24 V DC digital outputs, with a maximum load current of 100 mA per channel.

The common negative connections are grouped in blocks of 16 channels, so field wiring should account for these electrical grouping arrangements.\u003c\/p\u003e\n\u003cp\u003eThe fallback selection applies commonly to all output channels rather than allowing separate HOLD, OFF, or NO settings for individual channels.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Is the NFDV561-P50 a sourcing or sinking digital output module?\u003c\/p\u003e\n\u003cp\u003eA: It uses a current-sink output configuration. Field loads must be connected with the appropriate external 24 V DC supply and polarity.\u003c\/p\u003e\n\u003cp\u003eQ: What is the difference between NFDV561-P50 and NFDV561-P51?\u003c\/p\u003e\n\u003cp\u003eA: The P50 version is the general-purpose configuration without explosion protection or the ISA Standard G3 option. The P51 version includes the ISA Standard G3 option. These configurations should not be treated as interchangeable without checking the applicable installation requirements.\u003c\/p\u003e\n\u003cp\u003eQ: What happens to the outputs when a fallback condition occurs?\u003c\/p\u003e\n\u003cp\u003eA: The module supports three fallback selections: HOLD maintains existing output states, OFF resets all output channels, and NO performs no fallback action. The detection time is 4 seconds, and one fallback selection applies to all channels. \u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":68891990294770,"sku":"NFDV561-P50","price":235.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0730\/5589\/5794\/files\/EB402-50.jpg?v=1793846303","url":"https:\/\/www.petrospare.com\/products\/yokogawa-nfdv561-p50-digital-output-module","provider":"Petro Spare Industrial Limited","version":"1.0","type":"link"}
