Siemens Reyrolle 7PJ13 Trip Circuit Supervision Relay

Product Details

The Reyrolle 7PJ13 trip circuit supervision relay monitors the integrity of circuit-breaker trip coils and wiring in low and medium-voltage networks for reliable protection system operation. Prevent critical failures by continuously monitoring your trip circuits. The Reyrolle 7PJ13 detects faults like auxiliary voltage loss or circuit breakage to generate immediate alarms. It also alerts you if a trip signal fails to operate the breaker for timely intervention. Enjoy continuous supervision across pre-closed, post-closed and latched trip conditions. The universal voltage ranges offer broad applicability. The compact 96 mm x 48 mm design enables flush mounting, and clear LED status provides easy integration and quick checks. Key benefitsProtect your system Supervise the integrity of your circuit-breaker trip coil and wiring circuits in low and medium-voltage networks. This proactive monitoring helps prevent critical failures and protects your electrical systems. Detect faults quickly Detect trip circuit failures promptly, including disconnected supplies or open circuits. Receive immediate alarms for auxiliary voltage loss and circuit breakage for rapid response. Streamline system integration Integrate binary outputs with numerical protection relays to indicate faulted circuits to remote SCADA systems. This connectivity provides comprehensive oversight and simplifies fault management across your network. Featured capabilities Trip circuit monitoring The 7PJ13 connects to a circuit-breaker, monitoring trip circuit positions. It alarms if the trip circuit supply disconnects or becomes an open circuit. Measure continuity with a 0.7 mA to 1.5 mA supervision current.  Voltage ranges Use a universal auxiliary voltage range from AC 24 V to AC 240 V and DC 24 V to DC 240 V, with very low power consumption under 4 W.  Continuous supervision Maintain continuous supervision of the trip circuit in pre-closed, post-closed, and latched trip conditions. Detect faults like auxiliary voltage loss and circuit breakage in supervised circuits for reliable operation.
