Surface-mounted, unpopulated module housing for individual modules in a modular design. Housing made of solid steel sheet. The upper part of the housing is powder-coated in RAL 9010 and can be easily placed on and removed, as no screws are used for fastening. A potential-free connection is possible via a contact pin. Additional strain relief at the lower part of the housing using cable ties. Suitable for direct wall mounting, as a desktop device, and for DIN rail mounting with the mini FS DIN rail adapter. The bottom of the 3-port and 4-port housing can be removed, with additional fastening through a 60 mm mounting clearance. Optionally available and compatible with all housings: mini splice plate. Optional: 2 x 12 housing: strain relief for patch cables. Variants: 3, 4, 6, 8, 12, 16, and 2 x 12 ports.
