ABB DSCL110A (57310001‑KY) Redundancy Control Unit for Advant OCS / MasterPiece DCS System

Description

ABB DSCL110A (57310001‑KY) Redundancy Control Unit for Advant OCS / MasterPiece DCS System

Product Details

The DSCL110A, part number 57310001‑KY, is a dedicated rack‑mount redundancy control unit for ABB Advant OCS and MasterPiece legacy DCS platforms. It establishes high‑speed synchronization link between primary and standby controller pairs, implementing 1:1 hot‑standby redundancy architecture. It continuously synchronizes runtime database, logic state and process variables between two controllers. Once primary controller suffers power failure, CPU fault or communication breakdown, it triggers automatic bumpless failover within ≤100 ms without interrupting field control outputs. Powered by 24 VDC, it adopts Eurocard plug‑in structure supporting hot‑swap maintenance. Front‑panel LED indicators display master‑standby role, link status and fault alarms. CE‑certified EOL hardware, widely used as spare‑part and retrofit component for old‑generation ABB DCS installations in process industries.

Key Features

1. Specialized redundancy control hardware for ABB Advant OCS / MasterPiece DCS, realizes 1:1 hot‑standby controller configuration.
2. Fast bumpless switch‑over within 100 ms upon primary‑side failure, avoids process disturbance and production downtime.
3. Dedicated high‑speed link keeps full synchronization of runtime data, logic status and process variables between dual controllers.
4. Comprehensive fault‑detection mechanism, monitors CPU health, power status and inter‑controller link quality in real‑time.
5. Hot‑swap capable rack‑mount card design, allows module replacement without shutting down DCS control rack.
6. Multiple front‑panel LED status lamps for master‑standby identification, link activity and fault visual diagnosis.
7. Industrial‑grade hardware with wide operating temperature range, adapts to long‑term continuous‑running factory cabinet environment.
8. CE‑compliant, perfectly compatible with legacy ABB Advant controller series for system retrofit and spare‑part upgrade.

Main Functions

1. Build high‑speed synchronization channel between primary and standby DCS controllers for hot‑standby redundancy setup.
2. Real‑time mirroring of process database, logic execution state and I/O status between paired controllers.
3. Detect various primary‑controller faults including power loss, hardware error and communication failure.
4. Trigger automatic bumpless failover, switch control authority to standby controller without output fluctuation.
5. Report redundancy‑related fault and diagnostic information to host DCS system for alarm processing.
6. Visually indicate master‑standby working role, communication link and fault condition via front‑panel LED indicators.
7. Support hot‑swap maintenance, module replacement without interrupting running process‑control logic.
8. Cooperate with Advant OCS controllers to improve whole‑system availability for critical continuous‑process industrial sites.
