It acts as a passive, high-reliability electrical baseplate engineered to host redundant Optical ModuleBus Modems (such as TB840 or TB840A), providing seamless routing for system logic power and dual-line communication paths across parallel hardware layers without any active electronic components on the board itself.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eProduct Type: Module Termination Unit (MTU) for Redundant Configuration\u003c\/li\u003e\n\u003cli\u003eModel Code: TU848\u003c\/li\u003e\n\u003cli\u003ePart Number: 3BSE042558R1\u003c\/li\u003e\n\u003cli\u003eManufacturer: ABB\u003c\/li\u003e\n\u003cli\u003eSystem Compatibility: S800 I\/O Family (Connects dual TB840\/TB840A Modems to Redundant I\/O clusters)\u003c\/li\u003e\n\u003cli\u003eCommunication Protocol Support: ABB's ModuleBus\u003c\/li\u003e\n\u003cli\u003eRedundancy Support: Yes (Module Redundancy and Line Redundancy capability)\u003c\/li\u003e\n\u003cli\u003eNominal Supply Voltage: 24 V DC (Acceptable range: 19.2 to 30.0 V DC)\u003c\/li\u003e\n\u003cli\u003eMaximum ModuleBus Power Current: 5 V @ 1.5 A, 24 V @ 1.5 A distribution\u003c\/li\u003e\n\u003cli\u003eRated Insulation \/ Dielectric Test Voltage: 50 V \/ 500 V AC\u003c\/li\u003e\n\u003cli\u003eAcceptable Wire Sizes: Solid\/Stranded 0.2 to 2.5 mm² (24 to 12 AWG)\u003c\/li\u003e\n\u003cli\u003eIngress Protection Rating: IP20 (IEC 60529 Compliant)\u003c\/li\u003e\n\u003cli\u003ePhysical Dimensions: 18.6 cm x 12.4 cm x 4.7 cm\u003c\/li\u003e\n\u003cli\u003eProduct Net Weight: 0.45 kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation Notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSnap the TU848 MTU firmly onto the standard horizontal cabinet DIN rail until the structural grounding springs lock tightly against the metal frame.\u003c\/li\u003e\n\u003cli\u003eSet the localized rotary cluster address switch to the exact node designation assigned within the master controller software configuration.\u003c\/li\u003e\n\u003cli\u003eAdjust the mechanical alignment keys using a flat tool to mirror the profile of the target S800 redundant modems prior to module insertion.\u003c\/li\u003e\n\u003cli\u003eTerminate field power lines and communication cables into the compression screw blocks, ensuring proper wire strip lengths to maintain IP20 electrical safety boundaries.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":53620811890872,"sku":"TU848","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0935\/6132\/3704\/files\/TU847_AAAr270.png?v=1782208111","url":"https:\/\/www.globalpetroparts.com\/products\/abb-tu848-3bse042558r1-module-termination-unit","provider":"Global Petro Parts Automation","version":"1.0","type":"link"}
