BTA05.2-DB

The BTA05.2-DB, Bosch Rexroth Indramat, BTA05 Machine Control Boards control board delivers robust AC switching and motor control in a compact, panel-mount format. Featuring a Repetitive Peak Off-state Voltage (VDRM) of 500 V and a Peak On-state Voltage (VTM) of 1.7 V, the unit withstands challenging load conditions while minimizing conduction losses. Its Operating Temperature Range of –40°C to +125°C ensures stable performance in extreme industrial environments, from sub-zero cold chambers to high-heat processes. The board’s Product design 5.2 DB configuration builds on the proven BTA05 family, offering seamless compatibility in existing Bosch Rexroth Indramat systems.

Incorporating a Gate Trigger Current (IGT) of 35 mA and a Gate Trigger Voltage (VGT) of 1.3 V, the BTA05.2-DB guarantees precise control over thyristor conduction, while its Holding Current (IH) of 15 mA prevents unintended turn-off under transient loads. The Critical Rate of Rise of On-state Current (di/dt) of 50 A/µs enables rapid load engagement, and its Surge Peak On-state Current (ITSM) of 40 A absorbs short-duration current spikes without damage. A continuous On-state RMS Current (IT(RMS)) rating of 4 A balances thermal management with power density, and the Isolation Voltage of 2500 V RMS protects against high-voltage coupling in multi-module racks. Robust Through Hole mounting simplifies integration into control panels, while its varnished aluminum housing extends operating life by resisting corrosion and mechanical wear.

Engineers value the BTA05.2-DB’s seamless integration with Bosch Rexroth Indramat operator panels such as the BTV05, enabling centralized diagnostics and parameter adjustments. Its IP65 protection rating and adherence to DIN 40 050 and IEC 529 standards ensure dust-tight, water-jet resistance for reliable field service. Deploying this board streamlines system architecture, lowers maintenance overhead, and enhances uptime across diverse industrial automation applications, from process control to material handling.
