Abstract

An electronic expansion module which has at least one circuit board, that 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, with the expansion module inserted into an opening formed on a side of the housing of an electrical field device for use in industrial control, the circuit board of the expansion module does not have any conductive connection to the electrical field device except in the contact region so that reliable electrical isolation between the interior of the device and the user is ensured.
