According to the description on the manufacturer's original packaging, it is a \"Terminal bus extension, coupler terminal\" \u2014 i.e. a terminal that couples and extends the internal K-Bus between Beckhoff I\/O modules. The product is intended for automation system integrators, maintenance departments, and service teams involved in upgrading or repairing existing installations based on KL-series couplers and modules.<\/p>\n<p>The terminal comes in a version approved for potentially explosive atmospheres \u2014 the II 3G KEMA 10ATEX0075X Ex nA II T4 marking on the housing indicates it is intended for operation in gas atmospheres (category 3G).
