Description
Product Introduction & Engineering Value
When turbine-generator sets or medium-voltage utility feeders experience critical fault conditions, split-second trip logic relies entirely on the processing core of the REG216 protection rack. The ABB 216VC62A HESG324442R13 functions as the master digital signal processing engine and communication bridge within the RE. 216 system. Running a high-efficiency 32-bit architecture, it continuously aggregates field data, runs protection algorithms, and manages high-speed parallel bus communications.
Field engineers rely on the 216VC62A for its rock-solid data integrity under severe electrical noise environments. Featuring onboard Flash EPROM for settings retention and a built-in gold capacitor memory buffer, the module safeguards trip logs, event sequences, and disturbance recorder data during total auxiliary station power loss.

Field Application & The “Trench” Experience
During a routine testing window at a hydroelectric facility, a generator protection cubicle suffered an auxiliary DC power dip during a breaker trip scheme test. While the system recovered, the station’s SMS (Substation Monitoring System) lost communication with the main REG216 rack. Diagnostic interrogation via the front 25-pin port revealed a corrupted internal RAM bus handler on the legacy 216VC62 processor board.
Replacing the module with a verified 216VC62A HESG324442R13 board cleared the bus failure. Thanks to the onboard gold capacitor storage, historical fault records were fully preserved, allowing plant engineers to pull the exact disturbance data using EVECOM software without losing critical event history.
Critical Application Scenarios:
- Utility Scale Hydro & Steam Generator Protection: Serves as the central trip decision engine in REG216 protection systems.
- Substation Automation Systems (SAS): Manages inter-rack parallel bus communications and station control bus bridging.
- Large Motor & Power Transformer Protection: Executes fast differential and overcurrent logic across complex multi-bay protection networks.

Transparency SOP: QA & Testing
- 1. Mechanical & Connector Inspection: Every module is checked for backplane pin straightness, ceramic component health, and front panel 25-pin RS-423 port integrity.
- 2. Power-Up & Gold-Cap Verification: The card is installed in a powered test rack to measure the 24V supply rails and test the onboard gold capacitor’s ability to hold RAM voltage during cold shutoffs.
- 3. Bus Communications Testing: The B448C parallel bus is exercised to verify handshake protocol execution and error-checking capabilities.
- 4. RS-423 & PC Interface Diagnostics: Communication is established using EVECOM diagnostic tools over the front serial port across all supported baud rates.
The Veteran’s Tech Trap Guide
- ⚠️ Do Not Swap Under Auxiliary Power: Swapping a 216VC62A card while the 216NG power supply is active can cause severe backplane voltage spikes. Always shut down both primary and redundant 216NG supply switches before pulling or inserting the card.
- PRO TIP: If the front-panel RS-423 communication fails, check your PC cable adapter. The 216VC62A uses an RS-423A / CCITT V.10 interface (unbalanced ±4.5V levels). Standard RS-232 adapters can occasionally drop bits if cable lengths exceed recommended specifications.
- ⚠️ Gold Capacitor Shelf Life: If replacing a board that has sat in storage for over two years, allow the module to remain powered in the rack for at least 12 hours. This fully charges the gold condenser before relying on it for event list backup.
Dynamic FAQ
Q: Is the 216VC62A HESG324442R13 compatible with both REG216 and REC216 racks?
A: Yes, the 216VC62A processor card is standard hardware across both the REG 216 generator protection and REC 216 control architectures.
Q: Will installing a replacement 216VC62A wipe my protection settings?
A: Protection parameters are stored in non-volatile Flash EPROM. However, when installing a replacement card, settings must be uploaded or transferred from your backup configuration using EVECOM/EVEWin software to match your site-specific single-line requirements.
Q: What is the function of the gold capacitor on the board?
A: The gold capacitor provides back-up energy to volatile RAM in the event of an auxiliary DC power loss, keeping event logs and disturbance recorder data intact until power returns.
Q: Does your surplus stock include a warranty?
A: Yes, all our New Surplus and reconditioned ABB 216VC62A modules carry a comprehensive 12-month replacement warranty.
