Product Description:

The BTA20.3-NA-WA-VA-BS is BTA20 Machine Control Board and manufactured by Rexroth Indramat. It offers stable and effective automation to industrial machines and offers top quality performance to different machine control purposes. It has 8 input/ output addressable channels that makes it simpler to interface with other control systems and devices.

The BTA20.3-NA-WA-VA-BS control board is well-designed, resistant in protection and efficient in operation. Its level of communication is also flexible since it can be converted to both RS232 and RS422/485 which can be compatible with many industrial systems. The front panel rating is IP65 which allows installation in environments with potential exposure to environmental elements. The BTA20.3-NA-WA-VA-BS machine control board weight is about 2.1 kg. The overall heat dissipation of this control board is 10W. Its housing has an IP20 rating which offers protection against dust and provides adequate safety for internal components. The front panel itself is made out of lacquered aluminum and is covered all over by a chemically resistant polyester foil to make it even sturdier. The board has INTERBUS-S/BT-BUS bus system whose communication supports up to 20 lines. It improves data transmission speed and reliability. The module is ideal for use in demanding industrial environments requiring consistent and accurate control.

The BTA20.3-NA-WA-VA-BS machine control board is compact with dimensions of 407 mm x 169 mm x 100 mm. Its light grey color RAL 7035 blends well with most industrial environments. It is engineered to meet the needs of industries that demand high performance flexible and reliable machine control solutions. It is an important component for streamlining automated processes which offers a high level of precision in industrial environments.
