The Allen Bradley 148542 Node Adaptor Board, part of the 1395 spare parts series by Rockwell Automation, is engineered for reliable PLC communication. It operates at 5 volts and functions effectively within an ambient temperature range of 0 to 60 degrees Celsius, while the storage temperature capability extends from -40 to 85 degrees Celsius. Designed for efficient data exchange, the board achieves a baud rate of 57.5 kilobytes and supports altitudes up to 3,300 feet, managing humidity levels between 5% to 95% non-condensing. Featuring key diagnostics, the board includes LED indicators for communication status and processor faults, alongside user-friendly DIP switch settings for configuration. The robust construction requires ESD protection and is recommended to be installed by a qualified technician to ensure optimal performance and safety.
