Abstract
An intrinsically safe field device of automation technology for use in an explosion-hazard area comprises two connection terminals for connecting a two-wire line; a sensor and/or actuator element for detecting and/or setting a process variable; and a field device electronic system that is connected to the first and second connection terminal and conducts a current supplied via the two-wire line via a current path. The field device electronic system is designed to transmit process variables detected via the sensor element via the two-wire line and/or receive a process variable to be set by the actuator element via the two-wire line The field device electronic system has a shunt resistor circuit with a shunt resistor and two diodes connected in parallel to the shunt resistor. The diodes are in the current path in the flow direction.
