Product Description:

The BTA20.4-ND-DC-VD-BS control panel is manufactured by Bosch and is designed to be easily integrated into systems that demand consistent control and communication interfaces. The control panel is designed to efficiently support automation processes.

The BTA20.4-ND-DC-VD-BS control panel delivers approximately 1.0 A of current and 18 W of power at its peak. Side by side, the panel measures 407 mm broad, 169 mm tall, and 119 mm deep. The mounting dimensions are 375 mm by 137 mm by 119 mm. The mass is around 2.1 kg. The varnished metal is concealed beneath the polyester foil that envelops the chemically resistant front panel. The front panel is protected to an IP65 specification. In terms of input and output, the control panel supports RS232, RS422, INTERBUS, and one of each. For 24 V inputs, the low-level data input range is 0-10 V, while the high-level data input range is 18-30 V. An input current of less than 10 mA is applied. The output current of each data output is 200 mA. These specifications enable automated control systems to effectively communicate and manage data. The servo motor should be stored at temperatures ranging from 20 to 60 degrees Celsius and used in a controlled setting between 5 and 45 degrees Celsius.

The BTA20.4-ND-DC-VD-BS panel can operate up to 1500 m altitude within an air pressure range of 860 to 1060 hPa. The panel from outside is a light gray shade that meets the RAL 7035 standard. When utilized in industrial automation applications, these specifications ensure dependable deployment even in locations with variable altitudes or storage conditions. When structural integrity and consistent electrical performance are critical, the control panel is the ideal choice.
