Product Description:
The BTA20.3-NE-LA-KB-BS is a Machine Control Board from Bosch Rexroth Indramat. The company manufactured this board for industrial automation. It permits modular panel setups with NE, LA, KB, and BS modules. It requires a supply input of 18 to 30 volts DC. It draws roughly 1.0 ampere at peak electrical usage. The electrical load consumption is nearly 18 watts maximum.
The physical size of the BTA20.3-NE-LA-KB-BS control board is 407 mm in width, 169 mm in height, and 119 mm in depth. Its mounting footprint measures 375 mm wide, 138 mm high, and maintains 119 mm depth. The Front surface protection complies with the IP65 standard. The board functions properly within +5 °C to +45 °C ambient temperature. The BTA20.3-NE-LA-KB-BS control board is composed of different modules. The NE module of this board accepts RS232 input voltage from ±5 to ±12 volts, and it includes a 5 V auxiliary output supporting up to 50 mA. The INTERBUS channel in the LA section of the board operates at 500 kBd speed. The data exchange bandwidth through INTERBUS equals 3 words, or 48 bits. The INTERBUS delivers 24 bits for output signals and 40 for input readings.
The Low digital input on the KB module of the BTA20.3-NE-LA-KB-BS control board is registered from 0 to 10 volts. Its high input is recognized within an 18 to 30-volt range. Each input pin on the KB module draws less than 10 mA. The digital output terminals issue 24 V DC signals. Each output supports up to 200 mA maximum current. The BS module contact in the board handles 24 V DC or 42 V AC switching. The switching current on the BS contact is 2A DC or 3A AC. RS232, RS422, and INTERBUS interfaces are provided for communication.
Frequently Asked Questions about BTA20.3-NE-LA-KB-BS:
Q: How does the modular structure of BTA20.3-NE-LA-KB-BS benefit maintenance?
A: Modules can be replaced or upgraded individually without disassembling the whole unit. This reduces downtime and simplifies troubleshooting.
Q: What is the purpose of 48-bit bandwidth in INTERBUS for BTA20.3-NE-LA-KB-BS?
A: It accommodates high-resolution sensor and actuator data transmission. This is vital for precise control in complex automation tasks.
Q: Why is the mounting footprint of BTA20.3-NE-LA-KB-BS smaller than its physical size?
A: This allows for space-efficient panel installations without compromising component accessibility. It supports optimized enclosure designs in constrained environments.
Q: Why is the RS422 output on the NE module limited to 60 mA on BTA20.3-NE-LA-KB-BS?
A: The 60 mA cap ensures signal integrity and prevents driver overloading. This supports consistent and interference-free differential communication.
Q: How does the BS module switching capability enhance BTA20.3-NE-LA-KB-BS functionality?
A: It allows switching between 24 V DC and 42 V AC loads. This enables flexible integration with different industrial actuators and sensors.
