KJ4001X1-BA2 VE3051C0 12P1562X042

The KJ4001X1-BA2 carrier provides two positions for one system power supply and one controller, or for two system power supplies. In a simplex arrangement, the controller occupies the right-hand position. The separate system power-supply module converts its input into the system supply used by the controller and I/O; the carrier itself is the mounting and interconnection component. VE3051C0 is the 2-wide carrier ordering reference, and 12P1562X042 remains part of the offered assembly identity.

The BA2 installation arrangement uses standard 35 mm T- or G-type DIN rail, with different latching screws for the two rail profiles. The heavier 15 mm-deep T rail is recommended for the equipment weight distribution. Adjacent carriers connect by sliding their side-mounted 48-pin connectors together, and the 2-wide carrier is positioned to the left of the 8-wide I/O carriers. Latch engagement and connector alignment must both be established before installing the mounted modules.

The horizontal-carrier system carries power and communication between the controller and I/O interfaces. A redundant controller requires an additional carrier; redundancy is a system arrangement involving the selected controllers, supplies and connections. Carrier extensions support layouts across separate rails, while grounding follows the installed enclosure and power-system design. Keep the supplied BA2 and X042 assembly identity distinct from later carrier revisions when selecting a replacement.
