700DC-R440Z24

The Allen-Bradley 700DC-R440Z24 Sealed Switch Relay is an electromechanical switching device specifically designed for applications where enhanced protection against the electrical sparks that are generated by the intrinsic switching operation is required. The electrical parts on the Allen-Bradley 700DC-R440Z24 Sealed Switch Relay are encapsulated in a vacuum chamber that isolates them from the external atmosphere, making this relay an ideal solution for the remote control of external loads operating in highly polluted, hazardous, or potentially explosive job sites such as oil and gas regulating and measurement stations, chemical dispensing areas, or other similar hazardous industrial locations. These relays have been certified for working in all industrial areas with Class 1, Division 2 Groups A, B, C, and D hazardous location classification types.

The Allen-Bradley 700DC-R440Z24 Sealed Switch Relay can safely operate within the recommended operating temperature range of -40 to 60 degrees Celsius (-40 to 140 degrees Fahrenheit). Even though these relays are specially designed for hazardous or explosive atmospheres, it is always advisable to mount the Allen-Bradley 700DC-R440Z24 Sealed Switch Relay inside a properly protected enclosure or panel, in order to maximize the safety measures for these types of operating atmospheres. No maintenance operations are needed for the internal contacts of the device under normal circumstances. The 700DC electromechanical relay switches with sealed contacts tend to have an extremely long lifecycle because they can effectively keep moisture and dirt away from their internal operating and electrical parts, which is the most common cause of malfunctioning in other relays and similar devices.
