Product Description:

The 105-095001-01 motion control card is manufactured by Pacific Scientific as part of the 105 Motion Control Cards series. It is installed in PC-based or embedded controllers to generate trajectories, interpret feedback, and coordinate discrete signals for a single servo or stepper axis in automated machinery. By integrating both motion sequencing and field-level I/O on one board, it lightens the load on the central PLC and keeps deterministic loops local to the drive.

At the hardware level, the board supports an axis count of 1, so its profile generator and encoder interface serve one independent drive. Motion programs reside in 32kx8 NVRAM, keeping sequences resident without external batteries. The controller exchanges setup data and run-time status through a RS-232/RS-485 serial port. Each parameter register is implemented as a 10-bit data word. Digital outputs use open-drain DMOS transistors that show a maximum on-resistance of 9.5 Ω at 125 °C, limiting dissipation when driving field coils. Inputs contain a 10 kΩ pull-up to +12 VDC, and their 100 µs RC constant debounces mechanical switches. Logic low is recognized below the 1.0 V threshold, while a new high state is accepted above 3.5 V, simplifying connection to 5 V or 24 V sensors.

The discrete interface provides 21 channels of bi-directional I/O that may be assigned as limit switches, drive enables, or user flags. Each output can sink up to 100 mA through the transistor stage, supporting direct actuation of indicators or low-power solenoids. The card operates from a 5 VDC user supply rail, and its logic section draws no more than 200 mA. Program retention is guaranteed for 10 years, and the non-volatile array permits unlimited write cycles, allowing frequent parameter or recipe updates without wear. These electrical limits, memory characteristics, and debounce features make the card suitable for long-life installations that demand deterministic motion and direct sensor wiring.
