INTRINSICALLY SAFE BARRIER BK MODULE
BK module 81.316 is a component of a computer, e.g. EMPC-08, designed for visualization and process control. The module is an intrinsically safe barrier between the computer and the Ex ib keyboard. The module must be installed in a flameproof housing "d" with a degree of protection of no less than IP54. The module circuits used for connection to the keyboard are made in the "ib" category.
