A locking bar at the upper front edge fixes the I/O boards once they are inserted.
An I/O subrack can be powered by a single 5 V regulator unit or redundant 5 V regulator units
located at the rear of the subrack.
A connection unit with screw terminal blocks for field connection of the process signals is
provided for each I/O board. You can usually disconnect process objects individually or in
groups with a disconnectible type of terminal block. The connection units are connected to the
I/O board via standard cables and are mounted in the rear plane of the cabinet.
