Controller works in extreme environments

Allen-Bradley ControlLogix-XT (Extreme Environment) controller from Rockwell Automation operates in abusive environments.

03/22/2013


The Allen-Bradley ControlLogix-XT (Extreme Environment) controller from Rockwell Automation operates in a broad temperature spectrum, minus 25 C to 70 C, and meets ANSI/ISA-S71.04-1985 Class G1, G2, and G3, as well as cULus, Class 1 Div 2, C-Tick, CE, ATEThe Allen-Bradley ControlLogix-XT (Extreme Environment) controller from Rockwell Automation operates in very cold or hot temperatures, minus 25 C to 70 C, and meets ANSI/ISA-S71.04-1985 Class G1, G2, and G3, as well as cULus, Class 1 Div 2, C-Tick, CE, ATEX Zone 2, and SIL 2 requirements for increased protection against salts, corrosives, moisture, humidity, and fungal growth.

The controllers meet ISA Pollution Class G1, G2, and G3 standards. When used with Allen-Bradley Flex I/O-XT products, they provide a rugged environment control system that avoids the need for an air conditioner or temperature regulator.

Allen-Bradley ControlLogix-XT active controller components are separated on the backplane by vented faceplate segments that provide increased airflow, offer a thermal cushion, and help lower the need for air-conditioning panels.  Allen-Bradley ControlLogix-XT controllers are ideally suited for corrosive environments, such as those found in oil and gas, wind-turbine, and ship-building applications. They are also well-suited for steel mills, where machines are constantly exposed to extreme heat.
