Designs

The housings of head stations (fieldbus couplers or controllers) may differ, for instance in terms of:

• The connection level with or without field-side power supply (Eco)
• The operator control elements and indicators
• The specific fieldbus interfaces
• Further communication interfaces

The housings of the I/O modules may differ, for instance in terms of:

• The module width (12 mm, 24 mm or 48 mm)
• The structure of the wiring interface (CAGE CLAMP^® or Push-in CAGE CLAMP^® connections)
• Different indicators
• The number of power jumper contacts
• The fuse holder (supply module)
• The protective cover (distance module)
