Altitude Operating Conditions
The characteristics in the table below apply to the modules BMX DAO 1615 and BMX DAO 1615H 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.
General Characteristics
| CAUTION | |
|---|---|
OVERHEATING HAZARD Take into account the temperature derating of the discrete
I/O modules at the installation to prevent the device from overheating
and/or deteriorating. Failure to follow these instructions can result in injury or equipment damage. | |
