The unit converts internal control commands into physical contact closures, driving field loads such as solenoids, motor starters, and pilot indicators. Operating over 16 isolated channels, it manages switching voltages up to 110 VDC or 240 VAC while isolating backplane control logic from external power surges.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eNFDR541-P00\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eYokogawa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eJapan\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.3 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e33 x 127 x 127 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-10 to +55 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e780 mA at 5 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Type\u003c\/td\u003e\n\u003ctd\u003eRelay Output Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannels\u003c\/td\u003e\n\u003ctd\u003e16 output channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Type\u003c\/td\u003e\n\u003ctd\u003eRelay contacts (dry contact)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated Voltage Range\u003c\/td\u003e\n\u003ctd\u003e24 to 110 VDC \/ 100 to 240 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Switching Current\u003c\/td\u003e\n\u003ctd\u003e5 A per channel (DC), 3 A per channel (AC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation Voltage\u003c\/td\u003e\n\u003ctd\u003e2000 VAC (channels to power supply)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnection Type\u003c\/td\u003e\n\u003ctd\u003ePressure clamp terminal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Type\u003c\/td\u003e\n\u003ctd\u003eDIN rail or panel mount\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eChannel Isolation and Galvanic Relay Integrity\u003c\/h3\u003e\n\u003cp\u003eThe module utilizes an electro-mechanical relay architecture coupled with a 2000 VAC galvanic isolation barrier between individual channels and the backplane power rail. This physical decoupling blocks high-voltage field spikes, AC line noise, and common-mode voltage offsets from penetrating the backplane control bus. Channel-level switching circuits feature arc suppression pathways designed to handle inductive kickback from solenoid coils and switching relays without degrading internal contact surfaces.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What are the current rating differences when switching AC versus DC loads?\u003c\/p\u003e\n\u003cp\u003eA: Each individual relay channel supports up to 5 A for DC resistive\/inductive loads (24 to 110 VDC) and up to 3 A for AC loads (100 to 240 VAC).\u003c\/p\u003e\n\u003cp\u003eQ: Can channels with different operating voltages be mixed on the same terminal block?\u003c\/p\u003e\n\u003cp\u003eA: Yes, because the module provides galvanic isolation between channels up to 2000 VAC, separate relay channels can switch distinct voltage sources (e.g., 24 VDC on Channel 1 and 120 VAC on Channel 2).\u003c\/p\u003e\n\u003cp\u003eQ: What terminal interface is used for field device wiring?\u003c\/p\u003e\n\u003cp\u003eA: Field connections terminate via integrated pressure clamp terminal blocks, allowing direct wire insertion without requiring specialized crimp lugs.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the module on a standard 35 mm DIN rail or secure it to a control cabinet backpanel using the designated mounting chassis slots. Verify that backplane bus power is disabled before inserting or seating the module into the FCN\/FCJ controller rack.\u003c\/p\u003e\n\u003cp\u003eStrip field conductor insulation to the specified length and insert wire ends firmly into the pressure clamp terminal block, torquing clamp screws appropriately to prevent loose contact points. Route high-power AC output cables separately from low-voltage DC analog signal lines and communication buses within cabinet wiring trunks to prevent electromagnetic noise induction. Provide external transient voltage suppressors or flyback diodes across highly inductive field loads (such as heavy solenoid coils) to extend internal relay contact service life.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":43791702917210,"sku":"NFDR541","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/469.1_36d3bee4-8929-42a6-8bb7-c72ce3b6cc9e.jpg?v=1785987640","url":"https:\/\/www.spareoil.com\/ar\/products\/yokogawa-nfdr541-p00-stardom-fcn-fcj-16-channel-relay-output-module","provider":"SpareOil Automation","version":"1.0","type":"link"}
