Hardware Specifications

System Integration and Communication Architecture

• Backplane Bus Communication Velocity: Executes deterministic internal data exchanges across internal digital signal processors to maintain sub-cycle trip calculation execution.
• Profinet / EtherNet/IP Deterministic Networks: Supports real-time substation communication protocols including IEC 61850 and Modbus TCP/IP for synchronized station-bus integration.
• I/O Density Scaling: Accommodates modular input/output card slots for scalable digital, analog, and RTD temperature monitoring expansion.
• Firmware Flash Compatibility: Permits secure field-upgradeable firmware image flashing via front-panel port access without altering hardware base wiring.

Frequently Asked Questions (FAQ)

• Q: Can the internal power supply or I/O modules be hot-swapped while the relay is energized?

  A: No, module replacement requires complete de-energization of control power and input circuits to prevent internal short circuits and data bus corruption.

• Q: What is the maximum storage capacity for time-tagged event records within the internal buffer?

  A: The internal event recorder retains up to 512 time-tagged events alongside high-speed waveform capture and disturbance recording logs.

• Q: How does the hardware handle corrosive environmental conditions?

  A: The hardware option configuration incorporates conformal coating to protect printed circuit assemblies against severe industrial and chemical exposure.

Field Installation Guidelines

• Ensure the enclosure chassis earth stud is connected directly to the substation ground bus using a low-impedance copper conductor.
• Verify control power input voltages fall within the specified 70-265 V AC or 90-300 V DC range before closing supply breakers.
• Terminate all current transformer and voltage transformer secondary shields exclusively at the designated panel ground bar to mitigate electromagnetic interference.
• Maintain clear airflow around the housing to facilitate natural convection cooling across the wide operating temperature range.
