Description
Product Features
-
Optimized Matching Assembly Design
Every component is designated for coordinated operation in generator protection circuits. The hardware layout and signal timing are tuned to match REG216 protection logic, eliminating compatibility risks caused by mismatched separate modules and ensuring consistent signal transmission among protection units.
-
Comprehensive Galvanic Isolation Performance
Built-in multi-stage isolation circuits separate primary CT/PT circuits from electronic control circuits. It effectively blocks surge voltage and transient interference transmitted from power circuits, avoiding damage to core protection boards and preventing protection maloperation under grid disturbance conditions.
-
High-reliability Relay & Optocoupler Interface
216GD61A provides potential-free trip relays and optocoupler input channels. Trip contacts support direct driving of circuit breaker trip loops, while optocoupler circuits realize safe collection of external status signals, meeting the high safety requirements of power plant primary and secondary equipment interlock.
-
Precision Analog Signal Conditioning
Support conversion and trimming of AC current and voltage signals from transformers. Stable signal amplitude adjustment ensures the protection unit acquires accurate electrical parameters as the foundation for fault judgment, overcurrent, overvoltage and differential protection actions.
-
Multi-layer Electrical Protection Mechanism
Integrated surge absorption, overvoltage clamping, short-circuit and reverse polarity protection. The assembly can withstand transient overvoltage generated by switching operations and grid faults, improving the survivability of secondary equipment during power system failures.
-
Built-in Real-time Self-monitoring
Continuous detection of channel status, power supply quality and communication link. Fault codes and status indicators can quickly locate abnormal channels, wiring failures and module defects, shortening troubleshooting time during unit operation.
-
Harsh Environment Adaptability
Circuit boards adopt conformal coating treatment against humidity, dust and corrosive gas. All units comply with industrial EMC standards, capable of stable long-term operation in power plant control cabinets with vibration and electromagnetic interference.
- Standard Rack Mount Structure
Uniform form factor for cabinet slot installation. Support direct plug-in replacement without modifying wiring; modular maintenance reduces unit outage duration during equipment overhaul and upgrade.
