Patent number: 11009370Abstract: The invention relates to a method and to a safety circuit for safe limiting of consumption of electrical power in an electrical component of a field device. The consumption of the electrical power is controlled by separating the input path from a superordinated unit by the safety circuit according to a predetermined clocking, wherein the clocking is controlled by a control signal. In the case of no control signal, the power limiting is assured by separating the input path from the superordinated unit. In the case of a defective control signal, the power is limited by the safety circuit to a maximum power. Due to this type of control, the operating temperature of the electrical component remains always below a critical temperature. The field device may thus be used in explosion-endangered regions.Type: GrantFiled: June 26, 2017Date of Patent: May 18, 2021Assignee: Endress+Hauser SE+Co.
