The ABB CH-3185 3BHL000986P1006 is a high-availability controller module from ABB’s Symphony Plus series, specifically designed for large-scale power generation and transmission systems. This 64-bit redundant controller features quad-core ARM Cortex-A72 processors running at 1.8GHz, achieving 2ms deterministic cycle times for grid synchronization in 1000MW thermal power plants. The CH-3185 3BHL000986P1006 integrates 4GB ECC-protected DDR4 memory with battery-backed SRAM, ensuring zero data loss during abrupt power failures in substation automation.
As part of ABB’s Symphony Plus S+ Automation platform, this module supports native integration with IEC 61850-9-2LE Sampled Values and GOOSE protocols, enabling seamless communication with smart grid protection relays. Its -25°C to +70°C operational range with IP54 protection makes the CH-3185 3BHL000986P1006 suitable for outdoor switchyard installations. The hot-swappable design allows module replacement without interrupting turbine control sequences in combined cycle power plants.

Key Features and Advantages:
Grid-stable architecture: The CH-3185 3BHL000986P1006 employs phase-locked loop synchronization technology with ±0.001Hz frequency accuracy, critical for interconnecting regional power grids. Its <100μs redundancy switchover time prevents load shedding during fault conditions.
Cyber-secure operation: Integrated Trusted Platform Module (TPM 2.0) encrypts communication with substation HMIs, while whitelisting technology blocks unauthorized code execution. The module’s secure boot firmware meets NERC CIP requirements for North American power networks.
Energy-efficient design: Dynamic voltage scaling reduces power consumption by 40% during low-load periods in hydroelectric plants. The aluminum alloy housing dissipates heat without forced cooling up to 60°C ambient temperature.
Application Areas:
The ABB CH-3185 3BHL000986P1006 excels in:
- Power Transmission: 500kV breaker failure protection
- Renewable Energy: Solar farm STATCOM control
- Steel Production: Arc furnace harmonic compensation
- Oil & Gas: Compressor anti-surge protection
In offshore wind farms, this controller manages 200+ turbine pitch systems simultaneously. Nuclear plant applications utilize its seismic-certified design (IEC 60980) for emergency diesel generator control. The module’s <10μs timestamp accuracy enables precise fault location in 220kV transmission lines.

Installation and Maintenance:
Installation preparation: Before mounting the CH-3185 3BHL000986P1006, verify DIN rail integrity and ensure proper clearance (≥50mm) for heat dissipation in switchgear cabinets. Use ABB-recommended torque wrench (0.8Nm±5%) for power terminal connections to prevent arcing.
Maintenance recommendations: Perform firmware updates through Control Builder Professional using encrypted USB keys. Clean air vents biannually with dry nitrogen purge (≤0.2MPa pressure) in coal-fired power plant environments. Replace backup supercapacitors every 10 years for optimal hold-up time during blackouts.
