R2-SP-IC12 Segment Protector for Cabinet Installation

Segment Protector for Cabinet Installation R2-SP-IC12 The R2 Segment Protector with integrated diagnostics, a device coupler for DIN rail installation, connects 4 ... 12 instruments to the segment with intrinsic safety (Ex ic, Zone 2/Div. 2). Device connections in Zone 1/Div. 1 require additional methods of ignition protection. Short-circuit, jabber, and bounce protection isolates most fault condition types from the segment. The short-circuit limit is adjustable for maximum load with Ex ic for gas groups IIB and IIC. 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. Short circuit protection ensures proper operation of the segment in case of unwanted faults at the spur. Intrinsic safety at the spur enables work on devices with hot work permit. The integrated fieldbus terminator features a high-availability design. 4 ... 12 o
