Description
‑ Power Supply: Powered by REG216 rack back‑plane bus (5 VDC, 24 VDC)
‑ Power Consumption: ≤ 12 W
‑ Mechanical Structure: 6U Eurocard rack‑mount plug‑in board, metal front panel, back‑plane parallel bus connector, memory card slot on front panel
‑ On‑board Resources: Main CPU processor, program EPROM, parameter EEPROM, working RAM, event‑log RAM, real‑time clock, B448C parallel back‑plane bus interface, self‑diagnosis logic
‑ Communication Interface: Internal B448C parallel back‑plane bus; front‑panel service serial port for local commissioning tool connection
‑ Galvanic Isolation: Service serial port is electrically isolated from system internal bus
‑ Interfaces: Front‑panel service serial connector, memory‑card slot, back‑plane system bus connector
‑ Status LED Indicators: Power, Run, Module Fault, System‑alarm LEDs
‑ Weight: Approx 0.50 kg
‑ Executes full set of generator‑transformer protection algorithms, logic interlock and blocking‑condition judgment.
‑ Reads analogue sampled data from 216EA62 series module and binary input status from digital I/O modules over back‑plane bus.
‑ Generates protection trip and interlock commands, sends control instructions to output modules such as 216DB61, 216NG62 and 216NG62A.
‑ Manages protection setting‑parameter database, stores fault event records, disturbance records and real‑time time‑stamp for every event.
‑ Transmits measured values, event logs and system status to upper‑level SCADA via 216MB66 communication module. Supports local parameter commissioning via front‑panel service serial port.
‑ Comprehensive hardware self‑diagnosis: detects power‑supply abnormality, memory check‑sum error, firmware failure, back‑plane bus communication error and internal circuit fault, reports fault status.
‑ All protection function parameters are configured by external CAP2/316 commissioning software.
‑ Cannot operate independently without REG216 rack back‑plane, matched I/O modules and auxiliary power supply. Hardware revision B is pin‑compatible with later revisions C/D/E, with component‑level optimization for improved stability. Cannot be directly hardware interchanged with other REG216 plug‑in boards.
‑ Continuously monitors CPU runtime, memory integrity, back‑plane bus communication and module internal hardware health. Detected faults activate fault LED and block protection‑logic execution.
‑ No local numerical display; measured values, protection events and fault codes are retrieved via upper‑level HMI or local commissioning tool.
‑ Module hardware failure will cause complete shutdown of all generator‑transformer protection and control logic, trip and interlock functions are fully disabled, bringing severe safety risks for power‑plant generator‑transformer set.
‑ Back‑plane connector: Connect to REG216 B448C parallel back‑plane bus for data exchange with all other plug‑in modules.
‑ Front‑panel service serial port: Connect to commissioning PC for parameter setting, reading events and disturbance records.
‑ Front‑panel memory‑card slot: For firmware upgrade and parameter backup.
‑ Mounting: Plug‑in installation inside REG216 system rack
‑ Operating Temperature: 0 °C ~ +60 °C
‑ Storage Temperature: −40 °C ~ +85 °C
‑ Relative Humidity: 5‑95 %RH, non‑condensing
‑ Protection Class: IP20 (inside cabinet)
- 216VC62a processor unit (HESG324442R13/B)
Complementary parts: REG216 system rack and back‑plane, power‑supply supervision module 216NG63A, analogue‑input unit 216EA62, I/O modules, communication module 216MB66, field shielded signal cables, CAP2/316 commissioning software.
‑ Power off the whole rack before inserting or removing the processor module. Use shielded cables for service‑port wiring to reduce electromagnetic interference.
‑ For spare‑part replacement: Verify complete part number HESG324442R13/B. After replacement, confirm back‑plane bus identification, download protection parameter settings, verify protection‑logic execution, event‑recording and self‑diagnosis fault‑reporting function.
‑ Module hardware fault leads to total failure of generator‑transformer protection functions.
