It provides isolated 24 VDC transistor outputs for switching external field loads through current-sink output circuits. The module supports individual ON\/OFF control, output status monitoring, and configurable output fallback behavior for handling controller or communication-related fault conditions.\u003c\/p\u003e\n\u003ch3\u003eFunctional Description\u003c\/h3\u003e\n\u003cp\u003eThe NFDV551 provides 32 digital output channels for transmitting discrete control commands from the FCN controller to external field devices. Typical connected loads include DC interface circuits, indicator devices, and other compatible 24 VDC control loads.\u003c\/p\u003e\n\u003cp\u003eIts current-sink output arrangement switches the load current through the output circuit toward the common negative reference. This requires the external load and field power supply to follow the specified wiring polarity.\u003c\/p\u003e\n\u003ch3\u003eOutput Characteristics\u003c\/h3\u003e\n\u003cp\u003eThe module uses isolated transistor output circuits, with the common negative connection arranged in groups of 16 channels. This arrangement separates the two output groups electrically and defines the common wiring requirements for field connections.\u003c\/p\u003e\n\u003cp\u003eThe output status function reports the ON\/OFF state of the output channels. The specified status output response time is 3 ms or less. This value refers to status output response, not necessarily the complete response time of the controller-to-field control loop.\u003c\/p\u003e\n\u003ch3\u003eOutput Fallback Function\u003c\/h3\u003e\n\u003cp\u003eThe NFDV551 supports three output fallback settings:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHOLD: Retains the current output states when the fallback condition is triggered.\u003c\/li\u003e\n\u003cli\u003eOFF: Resets all output channels to OFF.\u003c\/li\u003e\n\u003cli\u003eNO: Performs no fallback action.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe fallback setting applies to all channels together rather than allowing a separate fallback selection for each channel.

The outputs use a current-sink configuration and are arranged in two groups of 16 channels.\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 HOLD, OFF, and NO fallback settings. HOLD retains the existing output states, OFF resets all channels, and NO performs no fallback action. The setting applies to all channels together.\u003c\/p\u003e\n\u003cp\u003eQ: Can the NFDV551-P11 drive AC loads directly?\u003c\/p\u003e\n\u003cp\u003eA: No. Its output circuits are specified for 24 VDC field loads. AC loads require an appropriate external interface or switching device selected according to the load and control circuit requirements.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":69285046812914,"sku":"NFDV551-P11","price":235.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0730\/5589\/5794\/files\/NFDV551-P112.jpg?v=1794379175","url":"https:\/\/www.petrospare.com\/products\/yokogawa-nfdv551-p11-digital-output-module","provider":"Petro Spare Industrial Limited","version":"1.0","type":"link"}
