Product Description:

The 502-03846-02 module is produced by Kollmorgen as part of the PIC900 Drives series. It occupies a half-slot position within the rack and serves as the primary control card that orchestrates axis drives in automated assembly lines, conveyors, and process machinery. By supplying low-voltage rails and program memory, it bridges the power stage of a PIC900 stack with plant-wide controllers, allowing coordinated motion sequences and status reporting. This card handles control functions within the stack rather than acting as a standalone power stage.

The board draws an AC input of 1 A and converts it into a combined output budget of 40 W that feeds its logic circuits and external sensors. Its physical profile of 61 × 305 × 213 mm fits inside shallow enclosures, and connection to the backplane is supported by a 3-terminal plug on the front edge. Separate regulators source 5.0 A at +5 V for digital ICs, 2.0 A at +15 V for analog conditioning, and 0.5 A at −15 V for differential reference stages. A 1.2 Ah, 3 V, 2/3 A lithium battery preserves user parameters during power loss. Rack occupancy of a half slot leaves space for adjacent I/O or communication cards, and a keyed input connector helps prevent reversed insertion. The front-edge plug arrangement also keeps the electrical interface accessible when the card is installed in a dense rack.

For host interaction, the PICPRO service port transmits at 57600 baud over an RS232 link, while the user port supports 19.2 kbaud RS232 with RTS/CTS handshaking for orderly data exchange. Separate serial channels allow service access and user communication to remain independent during normal operation. Hardware flow control helps regulate data transfer when the connected device cannot accept a continuous stream. The internal RTC maintains scheduling discipline with a tolerance of ±1 s/day.
