Product Description:
The 502-03876-02R4 power distribution module is manufactured by Kollmorgen for the PIC900 Drives series. Installed in a local or remote rack, it delivers regulated DC rails and communication paths that keep each servo amplifier in the string supplied and monitored. By consolidating these support functions, the unit simplifies cabinet wiring, reduces the number of external power supplies, and maintains the stable low-voltage logic required for precise automation sequences on packaging machines, pick-and-place gantries, and material-handling lines. The module supports the rack infrastructure rather than serving as a motor power stage, so connected amplifiers can share common control power and status signals.
Three isolated rails leave the card at fixed currents: a 0.5 A channel at -15 V for analog reference circuits, a 2.0 A rail at +15 V for sensor excitation, and a 5.0 A line at +5 V for digital electronics. Internal consumption is limited to 510 mA on the +5 V bus, leaving the remaining capacity available for neighboring drives on the same rack. Overall dissipation stays within 40 W, allowing convection cooling inside a sealed rack without adding separate forced-air hardware. Field terminations use a 3-terminal plug connector, while six twisted-pair pins carry differential data to attached nodes. Six status LEDs provide quick feedback on voltage presence, communication activity, and fault conditions during normal operation.
The enclosure occupies 213 mm of depth and only 61 mm of rack width, with a vertical span of 305 mm that matches other PIC900 carriers for consistent airflow. This narrow profile helps conserve rack space while preserving alignment with adjacent modules. A local rack span of 40 ft allows multiple axes to be grouped near the machine, while the backplane supports a 2000 ft remote rack span for decentralized I/O islands. Mechanical durability meets a shock limit of 15 g for 11 ms, so the card can tolerate handling shock and vibration during machine service.
