Description

TheABB 216MB66 Equipment Rack (HESG324511M1)is specifically designed for use within theREG216 protection system, providing a durable and structured mounting platform for multiple plug-in electronic modules. Installed in the hinged frame of a protection cubicle, it supports efficientfront-access insertion, testing, and maintenance. The rack incorporates a rear-mountedB448C parallel busfor communication between modules, along with standardized connectors for I/O and printer cables. Its robust mechanical construction ensures secure installation and stable electrical interfacing, even in environments subject to elevated vibration and electrical noise.
