Marshalling cabinets application

The smart choice for process
automation

Large process automation applications typically require the
use of a large number of digital or analog signals and sensors.
Indeed, marshalling cabinets ensure an important cross wiring
function, since the incoming field signal and the channel
quantity of the I/O card of the controller (DCS, large PLC’s) is
always different. They facilitate the maintenance operations
and ease the system modifications.

SNK aligned terminal blocks offering:
SNK series now features a full set of aligned terminal blocks
matching the marshalling panels typical configurations. Fuse,
disconnect, feed-through and ground terminal blocks with
identical profile are providing compact and convenient solu-
tion. With only 6 mm spacing, two aligned screwless jumper
channels, central large marking as well as aligned conductor
entries, they are perfectly adapted to alternative potential
distribution while still easy to connect.
