Product Description:
The BTA20.3-BA-NN-BA-NN control board is produced by Bosch Rexroth Indramat and belongs to the BTA20 Machine Control Boards series. It serves as a discrete signal concentrator inside automated machines, channeling local field wiring to a supervisory CNC or PLC. By mounting the electronics behind a sealed front panel, the board simplifies panel integration while providing a standardized platform for small batches or retrofit projects that need deterministic I/O processing without added communication overhead.
The signal interface is organized into 8 addressable inputs and 8 addressable outputs, allowing equal numbers of sensing and actuation points to be mapped by software. Because the board ships without a communication bus, commands and diagnostics are exchanged through its serial connectors. There is one RS-232 input port for direct serial access, plus one RS-422 input port and one RS-422 output port that support longer cable runs and differential noise immunity. Both side positions are specified as empty modules, giving the designer room to mount additional logic or power sections. The operator surface is covered by chemical-resistant polyester foil bonded to a sheet of varnished aluminum, ensuring key legends remain legible in environments exposed to coolant or mild solvents.
The front panel has an IP65 front panel rating, which helps keep dust and low-pressure water jets away from the user interface. The rear enclosure has an IP20 housing rating, which is appropriate after the board is installed inside a cabinet. The panel measures 169 mm front panel height and 407 mm front panel width, and these dimensions fit the standard slots of BTA20 racks while leaving clearance for ventilation above and below. These outside measurements also support consistent cutout sizes across different machine models.
