Product Description:

The 3NC154.60.2 is a motion and I/O controller card produced by B & R Automation for the System 2005 Controllers series. Installed in a backplane alongside CPU and power modules, it generates drive commands, captures feedback, and manages auxiliary signals for multi-axis machinery. By handling synchronized position, speed, and discrete control from a single board, the unit simplifies wiring and improves determinism in industrial automation cells such as pick-and-place stations, cutters, or indexing tables. This arrangement lets one board oversee axis coordination and supporting machine signals without requiring separate interface cards.

Each module supports three motion axes and supplies an analog drive command range of ±10 V with a per-channel load capability of 5 mA; combined with its 12 bit conversion depth, this enables proportional velocity or torque references to servo amplifiers. Five digital inputs per axis accept 24 VDC signals for home, limit, or probe functions. High-speed capture is handled by a synchronous counter that records edge events up to 600 kHz, and the depth of 32 bit prevents rollover during extended production runs. Incremental encoder tracks are processed at 150 kHz and must conform to 5 V differential levels, while a separate SSI channel handles absolute position data.

Program code is retained in a 2 MB FlashPROM, while variables execute from 2 MB DRAM to minimize cycle latency. The SSI interface can transmit position words up to 31 bits at 230 kBaud, matching high-resolution encoders used on packaging or assembly axes. A changeover relay on the board can switch currents up to 1 A for tasks such as brake release, and total demand on the 24 V bus stays below 6 W, easing power supply sizing. The card handles motion feedback, command output, and auxiliary switching within the same control slot.
