Product Description:
The BTA20.3-NC-DP-VD-BS machine control board is produced by Bosch Rexroth Indramat within the BTA20 Machine Control Boards series. Installed in modular automation racks, it executes numerical control tasks, processes discrete signals, and coordinates motion sequences for servo drives and pneumatic units. Acting as the central logic element, the board links sensors, operator panels, and fieldbus networks to support deterministic control in packaging lines, metal-cutting centers, and assembly systems without a separate PLC. It can also coordinate sequence timing between motion axes and peripheral actuators so machine events stay synchronized during operation.
Signal exchange with companion modules occurs over the proprietary BT backplane, and a maximum bus length of 50 m allows remote I/O mounting while preserving cycle timing. Internally, a 48-bit data width handles large status words and override data in a single transaction. For distributed peripherals, the integrated Interbus master operates at 500 kbaud, supporting fast sensor updates across the installation. The board provides 8 isolated inputs and 8 isolated outputs that use optocouplers to shield the CPU from external transients. Its physical dimensions include a depth of 119 mm and a height of 169 mm, while the card occupies a mounting envelope of 138 mm by 375 mm. These dimensions help the board fit into dense rack layouts where control and power modules share the same enclosure. A single mobile terminal port permits connection of handheld teach pendants, and four override code bits allow stepwise reduction of feed or spindle speed during setup.
The front panel has a protection rating of IP65, so the board resists airborne dust and low-pressure spray when mounted in a machine console. When fully wired, it manages 40 discrete inputs and 24 outputs for connection to external devices. Two usable enabling circuits furnish independent safety channels for power-off monitoring. The assembly spans 407 mm in overall width, which leaves clearance for neighboring drives and power supplies in the same rack.
