It accommodates CPU, power supply, I\/O, and extension-related modules within the controller assembly. The NFBU200 platform provides 10 function-module slots, two power supply slots, and a duplex SB bus for internal module communication.\u003c\/p\u003e\n\u003ch3\u003eFunctional Description\u003c\/h3\u003e\n\u003cp\u003eThe NFBU200 serves as the chassis and internal connection platform for the controller. It provides the mounting positions and electrical backplane connections required to assemble a control unit or extension unit from compatible function modules.\u003c\/p\u003e\n\u003cp\u003eIts internal SB bus distributes communication between installed modules. Depending on the system configuration, the base module can accommodate CPU modules, power supply modules, I\/O modules, and SB bus repeat or E2 bus interface modules.\u003c\/p\u003e\n\u003ch3\u003eModule Configuration\u003c\/h3\u003e\n\u003cp\u003eThe NFBU200 long base module provides the following configuration:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e10 function-module slots for CPU, I\/O, and extension-related modules.\u003c\/li\u003e\n\u003cli\u003e2 power supply module slots, allowing a duplex power supply arrangement with supported power supply modules.\u003c\/li\u003e\n\u003cli\u003eDuplex SB bus, providing the internal communication path between installed modules.\u003c\/li\u003e\n\u003cli\u003eSupport for use as either a control unit or an extension unit, subject to the installed modules and system configuration.\u003c\/li\u003e\n\u003cli\u003eCPU module installation occupies two function-module slots.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe available I\/O capacity depends on whether the unit operates independently or uses extension modules.

The mounting arrangement must be verified against the complete manufacturer ordering code before installation.\u003c\/p\u003e\n\u003cp\u003eThe base module also provides configuration settings for unit numbering and CPU duplex operation. These settings determine how the base module is assigned within the controller architecture and how CPU modules are configured.\u003c\/p\u003e\n\u003cp\u003eUnused slots require the appropriate dummy covers. Yokogawa identifies NFDCV01 for I\/O module slots and NFDCV02 for power supply module slots.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How many I\/O modules can the NFBU200 accommodate?\u003c\/p\u003e\n\u003cp\u003eA: The base module has 10 function-module slots. However, the actual I\/O module capacity is lower because CPU modules and extension-related modules also occupy slots. A standalone control unit can accommodate up to 8 I\/O modules in the applicable standard configuration.\u003c\/p\u003e\n\u003cp\u003eQ: Does the NFBU200 support redundant power supplies?\u003c\/p\u003e\n\u003cp\u003eA: Yes. It has two power supply module slots and supports a duplex power supply configuration. Yokogawa specifies that the NFPW444 power supply module is the supported model for redundancy in the relevant NFBU200 configuration.\u003c\/p\u003e\n\u003cp\u003eQ: What should be checked when replacing an NFBU200-015?\u003c\/p\u003e\n\u003cp\u003eA: Verify the complete ordering code, mounting arrangement, bus configuration, and installed CPU and power supply modules. The supplied designation NFBU200-015 does not directly establish all the suffix details in Yokogawa's published ordering-code tables, so the original nameplate should be checked before selecting a replacement.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":68890829029618,"sku":"NFBU200-015","price":235.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0730\/5589\/5794\/files\/NFBU200-S011.jpg?v=1793699844","url":"https:\/\/www.petrospare.com\/products\/yokogawa-nfbu200-015-base-module","provider":"Petro Spare Industrial Limited","version":"1.0","type":"link"}
