F650-N-F-L-F-2-G-1-HI-P-6E提供二次谐波检测，可用于屏蔽敏感元件，尤其是在变压器通电期间。该设置可以基于任何阶段、任何两个阶段、所有三个阶段或三个阶段的平均值。跳闸电路监控F650-N-F-L-F-2-G-1-HI-P-6E可用于监测断路器跳闸和闭合线圈及电路的完整性。监控输入监测蓄电池电压水平，而输出通过电路施加小电流监测跳闸和/或闭合电路的连续性。
F650-N-F-L-F-2-G-1-HI-P-6E
The rear of F650-N-F-L-F-2-G-1-HI-P-6E can add up to two communication cards. In addition to two identical ports COM1 and COM2, the board can also include a CAN bus communication port for connecting to remote CAN bus I/O modules (CIO modules). When the maximum number of I/Os available inside the relay (up to 64 inputs and 16 outputs) is insufficient to meet the requirements of a specific application, the CIO module is used to double the number of I/Os for F650-N-F-L-F-2-G-1-HI-P-6E. In addition to increasing the number of I/Os, the CIO module also allows F650-N-F-L-F-2-G-1-HI-P-6E to monitor signals located at remote locations, with only one connection between the two devices, significantly saving installation costs
F650-N-F-L-F-2-G-1-HI-P-6E
The remote I/O function provides a way to share digital point status information between F650-N-F-L-F-2-G-1-HI-P-6E or other IEC61850 compliant IEDs or controllers. Remote output seamlessly interfaces with remote inputs from other F650 devices through IEC 61850 GSSE messages. User secure peer-to-peer communication to develop complex solutions in distributed logic and I/O. In the event of abnormal behavior or phase loss in the CT, F650-N-F-L-F-2-G-1-HI-P-6E detects changes in zero sequence current to initiate CT fault induced events and outputs that can be used to block critical protection functions. This function can be suppressed through zero sequence voltage and grounding/sensitive grounding current.
F650-N-F-L-F-2-G-1-HI-P-6E
F650-N-F-L-F-2-G-1-HI-P-6E provides second harmonic detection and can be used to shield sensitive components, especially during transformer energization. This setting can be based on any stage, any two stages, all three stages, or the average of three stages. Trip circuit monitoring F650-N-F-L-F-2-G-1-HI-P-6E can be used to monitor the integrity of circuit breaker tripping and closing coils and circuits. The monitoring input monitors the battery voltage level, while the output applies a small current through the circuit to monitor the continuity of the tripping and/or closing circuit
