Function
The R2 Segment Protector, a device coupler for DIN rail installation, connects 4 ... 12 instruments located in Zone 2/Div. 2. to the segment with
intrinsic safety (Ex ic), energy limitation (Ex nL). Device connections in Zone 1/Div. 1 require additional methods of ignition protection. Short circuit
protection at each spur ensures proper operation of the segment during faults or hot work at the spur.
The T-connector at the trunk allows for exchange of a Segment Protector with no effect on the remaining segment. The terminator is mounted at
the 'T' and removed for network extensions ensuring proper termination.
All plugs feature retaining screws. LEDs and test access points simplify troubleshooting and help to decrease repair time. Any grounding and
shielding concept is possible based on FieldConnex enclosure solutions.
