MFT multifunction terminals allow maintenance in the hazardous area without a hot work permit. The module is removed in two steps: any ignition spark stays inside the flameproof enclosure and is extinguished, and the module is volt-free before it is lifted off. Once the module has been removed, wires can be disconnected even during operation, as live parts remain covered.

The plug-in modules fit on 2- or 4-pole DIN-rail sockets, ordered separately, and provide fuse protection for solenoids, alarm indicators and sounders, diode decoupling of power supplies, a simple OR gate, visible isolation of field devices, relay switching and PROFIBUS PA / FOUNDATION Fieldbus bus termination.

Key features
