F650-N-F-L-F-2-G-1-HI-P-6E的后部最多可增加两个通信卡。除了两个相同的端口COM1和COM2外，板卡还可以包含一个用于连接远程CAN总线I/O模块（CIO模块）的CAN总线通信端口。当继电器内部可用的最大I/O数量（最多64个输入和16个输出）不足以满足特定应用的需求时，使用CIO模块将F650-N-F-L-F-2-G-1-HI-P-6E的I/O数量增加一倍。除了增加I/O数量外，CIO模块还允许F650-N-F-L-F-2-G-1-HI-P-6E监控位于远程位置的信号，两个设备之间只有一个连接，从而显著节省了安装成本。 

在CT出现异常行为或相位损失的情况下，F650-N-F-L-F-2-G-1-HI-P-6E检测零序电流的变化，以启动CT故障引诱事件和可用于阻止关键保护功能的输出。该功能可通过零序电压、接地/灵敏接地电流来抑制。

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。

Up to two communication cards can be added to the rear of the F650-N-F-L-F-2-G-1-HI-P-6E. In addition to the two identical ports COM1 and COM2, the board CAN also contain a CAN bus communication port for connecting to a remote CAN bus I/O module (CIO module). When the maximum number of I/ OS available inside the relay (up to 64 inputs and 16 outputs) is not enough to meet the needs of a specific application, use the CIO module to double the number of I/ OS of the 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 the F650-N-F-L-F-2-G-1-HI-P-6E to monitor signals located in remote locations with only one connection between the two devices, resulting in significant savings in installation costs.

In the event of abnormal behavior or phase loss in CT, the F650-N-F-L-F-2-G-1-HI-P-6E detects changes in zero-sequence current to initiate CT fault inductive events and outputs that can be used to block critical protection functions. This function can be suppressed by zero sequence voltage, ground/sensitive ground current.

The 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 power-on. The setting can be based on any phase, any two phases, all three phases, or the average of all three phases.

Trip circuit monitoring

The 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 monitors the continuity of the tripping and/or closing circuits by applying a small current through the circuit.
