Characteristics of the Module

Altitude Operating Conditions

The characteristics apply to the module for use at altitude up to 2000 m (6560 ft). When the module operates above 2000 m (6560 ft), apply additional derating.

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

Environment and Operating Temperature

The BMXETM0200H module is a ruggedized module, also called hardened (H).

It can be used at extended temperatures -25...70 ºC (-13...158 ºF) and in harsh chemical environments.

This conformal coating treatment increases the isolation capability of the circuit boards and their resistance to:

Condensation
Dusty atmospheres (conducting foreign particles)
Chemical corrosion, in particular during use in sulphurous atmospheres (oil, refinery, purification plant, and so on) or atmospheres containing halogens (chlorine, and so on)

If this equipment is operated outside the -25...70 ºC (-13...158 ºF) temperature range, the equipment can operate abnormally.

CAUTION

UNINTENDED EQUIPMENT OPERATION

Do not operate this equipment outside of its specified temperature range.

Failure to follow these instructions can result in injury or equipment damage.

General Characteristics

WARNING

UNINTENDED EQUIPMENT OPERATION

Do not exceed any of the rated values in the characteristic table.

Failure to follow these instructions can result in death, serious injury, or equipment damage.
