Abstract

The invention discloses an intrinsically safe field device for process automation technology, comprising: at least one sensor element for detecting at least one measurand; a secondary coil for transmitting and receiving data—in particular, values derived from the measurand—from a primary coil, and for receiving power from the primary coil, wherein the secondary coil comprises first and second connections; a second coupling body that is designed to be complementary to a first coupling body, wherein the second coupling body comprises the secondary coil; and a circuit assembly that is arranged downstream of the secondary coil. Within the circuit assembly, Zener diodes are connected upstream of rectifier diodes.
