Product Description:
The BTV20.3PA-28B-45C-S-FW Panel is built by Bosch Rexroth for efficiency and durability as it offers low power consumption, robust environmental protection (IP65) and minimal input current which makes it suitable for demanding industrial control and monitoring applications.
The BTV20.3PA-28B-45C-S-FW panel supports multiple serial communication ports such as RS232 and RS422 in which RS422 output and input allow reliable differential signaling over longer distances, while INTERBUS connections facilitate data exchange with distributed I/O modules and field devices. It accommodates a wide spectrum of data transmission rates, from stationary up to 38.4 kbps which enables flexible communication speeds and its specified installation footprint (375 mm x 138 mm x 119 mm) determines the space required for affixing the panel within a machine or control cabinet. The upper and lower boundaries of operational thermal conditions are from +5 °C to +45 °C and it is finished in a neutral light grey tone (RAL code 7035). It accepts a flexible direct current input range between 18 - 30 V and it weighs a little over two kilograms which is light enough to handle during setup. It can be safely kept in a wide range of temperatures from -20 °C to +60 °C when not in use and for RS232 interface, it tolerates bipolar voltages typically used in serial communication.
This BTV20.3PA-28B-45C-S-FW panel emergency stop circuit can interrupt current up to 2 amps in DC or 3 amps in AC and it has a dedicated low-current 5V output which is designed to power lightweight communication modules or sensors connected through a data bus. Its RS422 interface emits signals using balanced voltage levels which provides a strong and noise-resistant transmission suitable for harsh environments or extended wiring.
Frequently Asked Questions about BTV20.3PA-28B-45C-S-FW:
Q: How does the RS422 differential signaling improve data reliability in the BTV20.3PA-28B-45C-S-FW panel?
A: RS422 differential signaling minimizes electrical noise, making communication stable over long cable runs. This is crucial in electrically noisy industrial environments.
Q: Why is INTERBUS support important in BTV20.3PA-28B-45C-S-FW operator panels?
A: INTERBUS allows seamless communication with distributed I/O systems, reducing wiring complexity. It also speeds up integration in modular machine setups.
Q: What makes the BTV20.3PA-28B-45C-S-FW panel suitable for harsh industrial environments?
A: The IP65-rated front panel and rugged build protect it from dust and splashing water. This makes it ideal for workshop and production-floor use.
Q: Why does the BTV20.3PA-28B-45C-S-FW include a chemical-resistant polyester front overlay?
A: The polyester foil resists oils, solvents, and cleaners used in industrial settings. This ensures long-lasting readability and durability of the interface.
Q: How does a 5V 50 mA bus output benefit connected devices on the BTV20 panel?
A: It powers lightweight sensors or signal converters directly from the panel. This reduces external power wiring and simplifies setup.
