摘要

Device for the intrinsically safe supply, control and / or evaluation of field devices in the explosion proof regionwith a current transfer means (60) for providing a galvanic separation between a controller (70) and the explosion proof region (90),with control-side terminals (51, 52) for connection with the control unit (70) andwith a first and a second field side connection (61, 62) for connection to be connected to field devices (92, 93), wherein the second field-side connection (62) is arranged, together with the first field side connection (61) field devices with a similar functionality, to be supplied to control and / or to evaluate,characterized by the,that the second field-side connection (62) is arranged, together with the first field side connection (61) field devices with digital input functionality, to be supplied to control and / or to evaluate,that a third field side connection (63) is provided, which is arranged, together with the first field side connection (61) field devices (92, 93) with digital output functionality, to be supplied to control and / or, and to evaluatethat signal setting means (20) are provided for activating and / or fixing a functionality of the second and / or of the third field side connection.
