Slide the unit down and press firmly against the 35 mm DIN rail until the mounting base snaps into place. Ensure the DIN rail locking screw is set to a horizontal position and verify that a zinc-plated chromate steel DIN rail is used to establish reliable ground continuity. Wire thermocouple leads using 24 to 14 AWG conductors, securing no more than two conductors per terminal pin. Torque terminal block screws strictly to 0.5-0.6 N m.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":45319769718899,"sku":"1734-TBCJC","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/1734-TB3_1200x1200_c563aeb8-4f9d-4d72-bf49-0c2f566b59a2.jpg?v=1785996413","url":"https:\/\/www.dcssupplier.com\/products\/allen-bradley-1734-tbcjc-terminal-blocks","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
