Product Description:

The 502-03814-40R1 controller card belongs to the PIC900 Drives series manufactured by Kollmorgen. Installed in the power interface chassis, it supplies the central processing and memory resources that coordinate axis control, diagnostic logging, and real-time drive sequencing in industrial automation cells. By combining a 32-bit microprocessor with dedicated program and user storage, the board handles motion profiles, status reporting, and communication with host PCs or PLCs without adding external computing hardware. This role places the unit at the center of each PIC900 rack, directing current loops and safety interlocks while monitoring feedback in demanding environments.

The card’s core is a 25 MHz clocked 80486DX CPU that executes drive control tasks, interpolation mathematics, and interrupt handling in deterministic cycles. Program instructions reside in 256K of application memory, while configuration tables can be expanded up to 1 MB through the onboard memory socket, allowing larger motion sets or custom routines. A standard math coprocessor is integrated to accelerate vector calculations and feed-forward loops, reducing execution latency at high update rates. Digital circuitry is powered from the backplane’s +5 V rail, and the logic draws 750 mA, a figure used when sizing cabinet power supplies and checking thermal loading.

For field integration, the board offers 2 × RS232 serial channels. The PICPRO maintenance interface supports throughput to 115200 baud, while the dedicated user port is limited to 19.2 Kbaud for reliable link-layer exchanges with HMIs or supervisory PCs. Logic isolation is preserved by symmetrical ±15 V rails, each sourcing only 10 mA, which helps limit noise transfer into analog stages. Mechanically, the module measures 41 mm wide, 213 mm deep, and 305 mm high, dimensions that match standard PIC900 card guides and leave airflow gaps between adjacent sections. No RAM memory is populated, and user data resides in 32 K of nonvolatile storage.
