FIELD: industrial automation.
SUBSTANCE: invention can be used in automation systems. Disclosed is an spark protection barrier comprising a power supply, a current measuring device, a semiconductor device, a stabilizer and a semiconductor switch for reducing power dissipated inside the power supply unit, increase of maximum capacity of intrinsically safe circuits due to provision of possibility to set operating parameters as close as possible to permissible intrinsically safe circuits.
EFFECT: higher reliability of spark protection.
