Product Description:

The 503-19184-00 is a rack assembly manufactured by Kollmorgen for the PIC900 Drives series of motion controllers. Installed inside the drive cabinet, the rack forms the backplane that unites power distribution and high-speed data lines for controller, communication, and I/O cards used by a PIC900 system. By housing these plug-in modules in a single frame, the rack establishes a fixed electrical reference and shortens internal wiring runs for coordinated-axis installations such as packaging machines and material-handling cells.

This unit is classified as a 5-slot rack, meaning the backplane offers module positions for plug-in cards. The hardware includes 5 total connector bays, but only 4 are intended for general-purpose I/O cards because the first position, labeled 1/2, is reserved for the combined CSM/CPU assembly. Positions 3-6 remain available for analog, digital, or network expansion modules, so the controller can be adapted to field devices without rewiring the processor. Aligning the processor at the left end keeps critical control logic close to the power supply traces, while the remaining slots use predefined addresses that simplify software configuration. Keyed rails help prevent misalignment during service.

The enclosure measures 9.0 in deep, 14.0 in high, and 8.8 in long, allowing the rack to fit on shallow panel shelves while still leaving clearance for rear cable bends and front card access. Each position terminates at a backplane receptacle with a 64-pin female connector that carries address, control, and low-voltage supply lines to the module edge fingers. The high pin count supports simultaneous signal routing for multiple axis channels and reduces the need for auxiliary ribbon cables. The enclosure height leaves room for top-down airflow around populated cards, which helps thermal performance in enclosed cabinets. Its depth and length also match standard Kollmorgen chassis brackets for compatible mounting arrangements.
