Mark VIe electronics are packaged in different locations world-wide and customized for a variety of protection classifications with and without ventilation and cooling. Controllers, I/O modules, power supplies, etc. are rated for -30 to 65°C (-22 to 149°F) at the electronics. To compliment the Mark VIe Control’s native I/O modules, a variety of fieldbus solutions are available with master communication gateways on the I/O network. These modules have slightly reduced operating temperature ratings: • PROFIBUS® Master Gateway: -20 to 55°C (-4 to 131°F) • CANopen® Master Gateway: -20 to 55°C (-4 to 131°F) • FOUNDATION Fieldbus™ Linking Device: 0 to 55°C (32 to 131°F) Modules with reduced operating temperatures should be mounted lower in the cabinet to avoid the natural temperature gradient from the bottom to the top of the enclosure. Control room equipment such as operator stations has an operating temperature range of 20 to 30°C (68 to 86°F). For shipping and storage, the controllers, I/O modules, power supplies, etc. are rated -40 to 85°C (-40 to 185°F), and control room equipment is rated 0 to 30°C (32 to 86°F).
