Product Description:
The BTA20.3-NE-DB-VD-BS is a printed control assembly produced by Bosch Rexroth Indramat as a member of the BTA20 Machine Control Boards series. Installed inside operator panels on transfer machines or assembly systems, the board coordinates discrete inputs and outputs, distributes override commands, and links the local station to the plant network. Its role in industrial automation is to translate hard-wired field signals into high-speed serial telegrams so that central controllers can make motion or sequencing decisions without extending long cable bundles onto the line.
For signal acquisition, the board provides 40 programmable digital inputs and 24 transistor-style digital outputs, giving a balanced channel ratio for typical sensor-to-actuator tasks. Internally, a parallel register with a width of 48 bits moves each scan of process data toward the communication coprocessor, and a buffer of 6 bytes on the BT-bus supports handshake and status bytes. The integrated auxiliary supply furnishes 200 mA at 24 V for light indicator loads or proximity switches, eliminating an external terminal block in small enclosures. Field communication runs simultaneously on INTERBUS-S / BT-BUS, letting the module participate on an existing Rexroth hierarchy while also exchanging cyclic data with third-party remote I/O. Eight inputs and eight outputs are galvanically isolated to separate noisy solenoids from sensitive logic rails, and the three-position key switch selects run, setup, or service modes without software tools.
The aluminum front plate is varnished for abrasion resistance and carries a local override potentiometer that can scale machine speed up to 120%. When the gasket is compressed against the cabinet door, the operator side is sealed to an IP65 rating. Overall board dimensions are 407 × 169 × 119 mm, while slotted guide rails accept the reduced mounting outline of 375 × 138 × 119 mm to clear neighboring cards. A remote bus clock of 500 kbaud keeps cyclic data intervals below two milliseconds even when the network is fully populated.
