Product Description:
The BTA20.3-NA-BW-VB-BS machine control board is produced by Bosch Rexroth Indramat for the BTA20 Machine Control Boards series. Installed inside CNC or special-purpose machine panels, the board coordinates local safety loops, manual overrides, and fieldbus communication so that higher-level motion controllers receive clear status information and can issue deterministic commands. Its mixed input and output channels, along with a built-in Interbus interface, make the product a compact node for 24-volt sensor signals, spindle and feed-rate adjustments, and emergency stop monitoring within industrial automation systems.
The board exchanges process data across the Interbus ring in 48 bits per cyclic frame, a width that matches the onboard I/O map without padding. Eight isolated 24-volt inputs let limit switches and proximity sensors enter the control logic, and a count of 8 corresponds to the same number of 24-volt transistor outputs. Each output can source up to 200 mA, which is enough to drive contactors or pilot lamps without external relays. Field communication remains stable at 500 kbaud, and the station is identified on the bus by code 3 for deterministic token passing. Two emergency-stop circuits interrupt all motion channels, three enabling circuits restore power after faults, and two dedicated override switches provide manual scaling while the Interbus connector occupies minimal cabinet depth.
The front panel carries a gasketed membrane that achieves IP65 protection, so coolant spray or airborne dust does not reach the electronics. Mechanical integration uses an overall size of 407 × 169 × 119 mm, while slotted holes provide a mounting footprint of 375 × 138 × 119 mm for front-side installation. Feed override is operator-selectable from 0% up to 120 %, allowing velocity trimming without modifying the NC program. The spindle channel starts at 45 % and rises to the same upper limit so cutting power can be adapted to material changes. All connectors remain behind the sealed door, which helps maintain the front rating during maintenance.
