Strip thermocouple extension wires to proper length before securing conductors into the 8 screw-clamp terminals. Avoid routing thermocouple leads in close proximity to high-voltage AC cables or drive outputs to prevent inductive noise interference with cold junction sensor readings. Ensure ambient temperature around the terminal block remains uniform by preventing direct drafts or nearby heat dissipation sources from disturbing the CJC reference node.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":45319762313331,"sku":"1734-RTBCJC","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/1734-RTBCJC_1200x1200_b431d8ff-504b-4d7a-9c3a-33a32b05b7a1.jpg?v=1785996437","url":"https:\/\/www.dcssupplier.com\/products\/allen-bradley-1734-rtbcjc-point-i-o-removable-terminal-block","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
