ABB DO801 3BSE020510R1 S800 I/O 16 Channel Sourcing Digital Output Module

As general-purpose conventional digital output spare of ABB S800 & System800xA DCS system, DO801 solves common on-site faults: control valve solenoid no response to DCS command, single channel permanent no output or frequent overload alarm, random intermittent output missing caused by grid surge and internal driver aging. Fully consistent with OEM original dimension, pin definition and terminal wiring layout, direct one-to-one swap replacement without modifying DCS control program and field cable layout, minimize unplanned production downtime during emergency breakdown maintenance.

• Thermal Power Plant: Auxiliary boiler feedwater valve, blower damper solenoid conventional control spare

• Petrochemical Refinery: Auxiliary process regulating valve, local field indicator lamp DCS control spare

• Cement Plant: Raw material conveying baffle valve, exhaust fan auxiliary interlock control spare parts
