Product Description:
The BTA20.3-NA-DK-BA-BS is a plug-in machine control board manufactured by Bosch Rexroth Indramat as part of the BTA20 Machine Control Boards series. Installed on the front door of a cabinet, it supplies local power and field connectivity for sensors, valves, and emergency circuits that need deterministic response inside automated assembly lines and material-handling stations. Its hardware consolidates user I/O, communication buses, and safety relays into a single compact carrier, simplifying cabinet wiring and module integration.
Its 24 V auxiliary rail can source 200 mA for proximity switches, while the logic rail delivers 50 mA at +5 V to small encoder modules. Field messages move across the dual-channel INTERBUS-S / BT-BUS backplane, and deterministic control signals reach the on-board digital matrix that offers 8 Inputs, 8 Outputs. The varnished aluminum front plate shields the electronics and, together with the gasketed keys, provides an enclosure rating of IP65 against dust and water jets. Physical space planning is aided by the overall size of 407 × 169 × 119 mm, while a reduced mounting footprint of 375 × 138 × 119 mm lets the carrier clear neighboring modules. One INTERBUS in-port and one out-port pass the ring through, eight plug-in sockets accept user boards, and each add-on may occupy 22.5 mm of panel width.
For safety, a redundant relay pair interrupts loads up to 2 A DC or 3 A AC within a permitted contact voltage of 24 V DC / 42 V AC, allowing the emergency-stop loop to remove power when required. The board continues to function without derating at site elevations up to 1500 m, supporting use in moderate-height locations. Data collection and diagnostics are routed through a mixed serial interface panel that provides 1 RS232 In, 2 RS422 links for HMIs and external diagnostic connections.
