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, front‑panel memory‑card slot
‑ On‑board Resources: Embedded main CPU core, program EPROM, setting‑parameter EEPROM, runtime RAM, gold‑cap buffered event‑log RAM, real‑time clock circuit, B448C parallel back‑plane bus interface, self‑diagnosis logic
‑ Communication Interface: Internal B448C parallel back‑plane bus; front‑panel isolated service serial port for local commissioning PC
‑ Galvanic Isolation: Front‑panel service serial port is electrically isolated from system internal logic 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 complete generator‑transformer protection algorithms, interlock‑logic and blocking‑condition judgment.
‑ Reads analogue sampled data from 216EA62 series and binary‑input status from digital I/O modules over B448C back‑plane bus.
‑ Generates protection trip and interlock commands, transmits control instructions to corresponding output modules.
‑ Manages protection setting‑parameter database, stores fault event records and disturbance waveforms, provides high‑precision time‑stamp for every event.
‑ Uploads measured values, alarm and event logs to upper‑level SCADA system via 216MB66 communication module. Supports local parameter download, event reading and disturbance‑data access through front‑panel service port. Memory‑card slot supports firmware upgrade and parameter backup‑restore operation.
‑ Comprehensive hardware self‑diagnosis: detects power‑supply abnormality, memory check‑sum error, firmware failure, back‑plane bus communication error and internal circuit fault, and reports fault status to system.
‑ All protection‑function parameters are configured by CAP2/316 commissioning software.
‑ Cannot operate independently without REG216 rack back‑plane, matched I/O modules and auxiliary power supply. Hardware revision F adopts upgraded component solution for improved EMC and temperature adaptability; pin‑compatible with B/C/D/E revisions within 216VC62a family, 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 suspend 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 outage 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, event reading and disturbance‑record access.
‑ Front‑panel memory‑card slot: Used for firmware upgrade and protection‑parameter backup‑restore.
‑ 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 (HESG324442R112/F)
Complementary parts: REG216 system rack and back‑plane, 216NG63A power‑supply supervision module, 216EA62 analogue‑input unit, digital I/O modules, 216MB66 communication module, field shielded signal cables, CAP2/316 commissioning software.
‑ Power off the whole rack before inserting or removing the processor module. Service‑port wiring shall adopt shielded cables with single‑end shield grounding to suppress electromagnetic interference.
‑ For spare‑part replacement: Verify complete part number HESG324442R112/F. After replacement, confirm back‑plane bus identification, download complete protection‑setting parameters, verify protection‑logic execution, event‑recording and self‑diagnosis fault‑reporting function.
‑ Module hardware fault results in total failure of generator‑transformer protection functions.
Generator and main‑transformer protection cabinets in thermal / hydro power plants; ABB REG216 numerical generator‑transformer protection‑control system; industrial spare‑part replacement for older hardware revisions.
