Product Description:
The BTA20.3-NE-LP-KA-BS machine control board is produced by Bosch Rexroth Indramat as part of the BTA20 Machine Control Boards series. Installed on the front of a cabinet door, the unit joins push-button control, key switching, and fieldbus communication so that programmable logic controllers can issue start, stop, and diagnostic commands without additional operator panels. Within industrial automation, the board provides the physical interface that links digital signals from sensors and actuators to the higher-level control system while shielding those circuits from environmental contaminants.
Data exchange with the central controller takes place over INTERBUS-S / BT-BUS, while separate RS-232 and RS-422 ports are available through 9-pin and 15-pin D-Sub connectors for local diagnostics. The unit provides 8 digital inputs that accept dry-contact or transistor signals and a matching set of 8 digital outputs for pilot lamps, contactors, or relays. Output bits can be switched at rates supported by the serial link, which reaches 38400 Baud. When mounted in a door, the varnished aluminum faceplate and chemical-resistant polyester overlay form a continuous seal with IP65 protection to keep dust and water spray away from the electronics. The visible height of the panel is 169 mm.
Mechanical clearances are provided for both the door cutout and the device itself. The board spans 407 mm across the front and extends 119 mm into the enclosure, while the mounting dimensions are 375 mm in width and 138 mm in height for a tight but accessible fit. Each digital output may source up to 200 mA, which allows direct operation of indicator lamps without interposing relays. A rotary switch with 3 keyed positions provides mode selection, such as automatic, manual, or lockout, without software intervention. The polyester foil and varnished faceplate help shield internal circuits, and the rigid printed circuit assembly supports stable RS-232 and RS-422 connections during cabinet-door operation.
