Continuous 125 V galvanic isolation barriers shield backplane logic processing from common-mode voltage spikes and field wiring noise. The mechanical chassis handles operational mechanical shocks up to 30 g without interrupting backplane contact continuity or signal integrity.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What wire gauge size is compatible with the cage clamp terminals on the 1794-TB2?\u003c\/p\u003e\n\u003cp\u003eA: The cage clamp terminals accept solid or stranded conductors ranging from 0.21 to 1.3 mm2 (24 to 16 AWG).\u003c\/p\u003e\n\u003cp\u003eQ: What is the recommended tightening torque for the terminal screws on the 1794-TB2?\u003c\/p\u003e\n\u003cp\u003eA: Terminal screws should be tightened to a torque rating between 0.56 and 0.79 Nm (5 to 7 in-lbs) to ensure secure electrical contact.\u003c\/p\u003e\n\u003cp\u003eQ: How many common and voltage terminals are available on the 1794-TB2 base?\u003c\/p\u003e\n\u003cp\u003eA: The unit features 18 common terminals and 2 dedicated voltage terminals to support 16 I\/O signal lines and field power distribution.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eSnap the 1794-TB2 terminal base onto a grounded TS35 DIN rail or secure it to an enclosure plate using mounting holes.\u003c\/li\u003e\n\u003cli\u003eSlide the unit laterally into the adjacent Flex I\/O terminal base until the internal Flexbus backplane connectors fully engage.\u003c\/li\u003e\n\u003cli\u003eStrip signal wire ends to specified length and insert them into cage clamp terminals, tightening screws to 0.56 to 0.79 Nm torque.\u003c\/li\u003e\n\u003cli\u003eAdjust the module mechanical keying dial on the base to match the position required for the targeted 1794 functional module.\u003c\/li\u003e\n\u003cli\u003eVerify field circuit voltage levels do not exceed the 125 VAC\/DC continuous rating or 10 A terminal current limits.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":52786950504728,"sku":"1794-TB2","price":270.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/3483\/3688\/files\/1794-TB22_Cocoai_0840aead-a26f-44ac-a242-ae2edbd05f41.jpg?v=1790650539","url":"https:\/\/www.innoplcsync.com\/products\/allen-bradley-1794-tb2-flex-i-o-cage-clamp-terminal-base-unit","provider":"InnoPLC Sync Co., Ltd.","version":"1.0","type":"link"}
