Environmental Durability and Mechanical Design

• This 1769-PB4 operates reliably in temperatures from 0 to 60 °C (32 to 140 °F) with adequate airflow.
• It uses an open-style design – no internal enclosure, so proper external housing is recommended.
• The module withstands operating vibration of 5 G at 10 to 500 Hz for robust industrial environments.
• Operating shock ratings: 20G for DIN rail mounting, 30G for panel mounting.
• Copper wire type must withstand 90 °C minimum insulation rating to ensure long-term safety.
• Shipping dimensions: 8 x 8 x 5 inches, easy to integrate into system panels.
• High EMC immunity ensures stable operation in electrically noisy industrial settings.
