Original ABB digital output board for ECS VME control rack, field actuator drive spare part.

Product Overview

086339‑501 is digital output board for ABB ECS VME‑bus control rack. It receives control commands from main controller, outputs discrete switching signals to drive on‑site solenoid valves, relays and contactors, completes interlock, sequence and equipment on‑off control. It communicates with rack backplane bus for real‑time command transmission. Conformal‑coated PCB resists vibration and electromagnetic interference in cabinet environment. Widely used as maintenance spare part for power‑plant and heavy‑industry automation control cabinets.

Key Features

• Multi‑channel digital output channels for driving field relays, solenoid valves and actuators
• Channel‑level isolation design, prevents field fault interference spreading to control rack
• On‑board self‑diagnosis circuit, LED indicators for channel status and fault prompt
• Real‑time command exchange via dedicated ECS backplane VME bus
• 6U VME plug‑in form factor, conformal‑coated PCB adapts to harsh cabinet conditions

• Supports hot‑swap operation within matched ECS rack for convenient on‑site maintenance
