Product Description:
The BTA20.3-NE-LB-KB-BS machine control board is manufactured by Bosch Rexroth Indramat for the BTA20 Machine Control Boards series. Installed on the front door of a control cabinet, the board serves as an interface layer between field devices and a central PLC, concentrating local inputs, routing serial data, and supporting key-switch safety functions. By placing terminations, status LEDs, and communication plugs on one rigid assembly, the unit simplifies wiring and improves diagnostic access inside automated machining cells, presses, and transfer lines.
The front panel provides 8 24 V inputs for sensors and 8 24 V outputs for lamps, solenoids, or contactor coils. Data exchange with the drive system is handled through the INTERBUS-S / BT-BUS backplane, and the board includes one Interbus in port and one out port so it can be placed at different positions in a ring topology. It also carries separate RS-422 receive and transmit channels for long-distance remote stations. Physically, the assembly is 119 mm deep, 169 mm high on the front face, and spans 407 mm across the door. When compressed against a fitted gasket, the enclosure reaches IP65 protection, which keeps dust and water jets away from the electronics during cleaning or cooling processes.
Mounting is completed on rear studs with a 138 mm vertical rise and a 375 mm horizontal spread, allowing direct retrofit into existing Indramat operator doors. A rotary selector on the panel uses a 2 NC + 2 NO contact block, so safety circuits can be wired without auxiliary relays. Programming access is provided through the dedicated socket marked BTC06.2. A service PC can also be connected to the adjacent 1 RS-232 port for parameter uploads and event logging without disturbing the fieldbus or RS-422 lines.
