Abstract
An electrical field device for use in industrial control with a housing, with at least one input, at least one output and an electronic circuit with a microcontroller, a memory and a circuit board. The electrical field device is easily adapted to different functions and conditions of use in that an opening is formed on one side of the housing for insertion of an electronic expansion module which has at least one circuit board, and in that the circuit board has a contact region with contacts for mechanical and electrical contact-making with mating contacts connected to the circuit board of the expansion, module and a circuit board recess formed such that an inserted expansion module does not have any conductive connection to the field device except in the contact region so that reliable electrical isolation between the interior of the device and the user is ensured.
