Characteristics for the BMX EHC 0200 Module and its Inputs and Outputs
Original instructions
About us
Ruggedized Version
The BMX EHC 0200H (hardened) equipment is the ruggedized version of the BMX EHC 0200 (standard) equipment. It can be used at extended temperatures and in harsh chemical environments.
For more information, refer to chapter Installation in More Severe Environments.
Altitude Operating Conditions
The characteristics in the table below apply to the modules BMX EHC 0200 and BMX EHC 0200H 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.
