Automation
Advanced automation capabilities enabling switchgear interlocking applicationsAdvanced automation capabilities enabling switchgear interlocking applications.

The C650 incorporates advanced automation features that replace multiple devices with a single unit and includes powerful programmable logic, communications, and SCADA capabilities that far surpass what is found in the average controller relay. The C650 provides seamless integration with other GE Multilin devices for comprehensive system automation and control.

Inputs and Outputs
The C650 offers a variety of different I/O configurations based on user’s need. A choice of 16 to 192 inputs and 0 to 48 outputs are available. Digital inputs may be user defined with a separate debounce and chatter time. Programmable “quasi“ analog input levels allow the use of different voltage levels in the same model via setting the requested thresholds. EnerVista software allows easy configuration of all the interlocking and switching sequences. A graphic HMI interface provides access to monitoring, metering and alarm panel screens.

Virtual Inputs/Outputs
Use virtual inputs and outputs in conjunction with the programmable logic capabilities of the C650 for unusual applications involving interlocks, blocking, or supervisory functions, to minimize the requirement for auxiliary components and wiring while making more complex schemes possible. The virtual inputs and outputs are digital signals associated with the C650 internal logic. Virtual inputs include signals generated remotely via communications. The virtual outputs are outputs of programmable logic equations used to customize the device. Virtual outputs can also serve as inputs to programmable logic equations.

Transducer Inputs
dcmA inputs are available to monitor system parameters such as temperature, vibration, pressure, wind speed, and flow.

Remote I/O
The remote I/O feature provides a means of sharing digital point state information between C650s or other IEC61850 compliant IEDs or controllers. The remote outputs interface seamlessly to the remote inputs of other C650 devices via the IEC61850 GSSE messaging. User secure peer-to-peer communications to develop complex schemes in distributed logic and I/Os.

Advanced Communications

The C650 incorporates industry-leading communication technologies making it one of the easiest and flexible feeder protection relays for use and integration into new and existing infrastructures. The C650 provides optional Parallel Redundancy Protocol (PRP), High Availability Seamless Ring (HSR) (IEC 62439-3) and also Rapid Spanning Tree Protocol (RSTP) (IEEE 802.1D) to increase network availability and reliability for critical applications.

The C650 supports industry leading, standard protocols enabling easy, direct integration into electrical SCADA and HMI systems. The protocols supported includes:

  • IEC 61850 Edition 2
