FieldConnex R2-SP-N* segment protectors

For Ex ic explosion protection, field instruments installed in Zone 2/ Div. 2 are connected to the FieldConnex R2-SP-N* Segment Protectors. Additionally, in combination with selected power supplies, the voltage is limited on the trunk line, and the R2 Segment Protector provides the current limitation for certified Ex ic instrument connections. For non-incendive (Ex nL) explosion protection every FieldConnex Segment Protector carries the appropriate certification.

The trunk is installed using protective wiring methods to prevent unintended disconnect or premature decay caused by corrosion or chemicals.
