Altitude Operating Conditions

The characteristics in the table below apply to the modules BMX DDI 3232 and BMX DDI 3232H for use at altitude up to 2000 m (6560 ft). When the modules operate above 2000 m (6560 ft), apply additional derating.

For detailed information, refer to chapter Operating and Storage Conditions.

(1) This characteristic is used to connect several inputs to the same module in parallel or to different modules for input redundancy.
NOTE: The power monitoring is effective only when the group input shares the same power supply. The module is able to customize sink/source by channel in case the power supply monitor function is disabled. Refer to the topic for additional information about usage of the power monitoring function and power supply connections.
NOTE: Confirm that the sensor power supply function is disabled in a 12 VDC application.
