Technical Specifications Back‑plane bus interface, on‑board non‑volatile memory. Auxiliary power 24 V DC, typical power consumption 8.2 W. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Conformal coated printed circuit board.
Functional Features Executes user application control logic program. Processes input‑output data from each I/O module. Completes interlock logic, sequence control and protection judgment. Supports program and parameter data power‑off retention. On‑board LED indicates running, standby and fault status. Built‑in hardware self‑diagnosis detects processor, memory and bus access faults.
Application Scenarios Core spare‑part for ABB Advant DCS controller rack. Applied in power plant, petrochemical industry large‑scale automation control system maintenance and spare‑part replacement.
Performance Parameters Stable real‑time logic operation performance. Reliable data exchange with I/O and communication modules. Accurate hardware fault self‑diagnosis capability.
Material Composition Multilayer glass‑fiber epoxy printed circuit board. Industrial processor chip, non‑volatile memory and logic peripheral assemblies. Conformal protective coating. Back‑plane plug‑in connectors.
Structural Characteristics Standard DCS plug‑in board structure. Board edge equipped with back‑plane bus connector. Reserved mechanical fixing holes. Weight approximately 0.75 kilogram.
Working Principle After power‑on, board completes hardware self‑test and system initialization. User control logic program is loaded from non‑volatile memory. It reads process data from each I/O module via back‑plane bus, executes logic calculation, and outputs control commands. Diagnosis circuit monitors hardware running status continuously.
Installation Requirements Cut off DCS rack auxiliary power before replacement. Insert 3BSE003816R1 into designated controller slot and tighten fixing screws. Confirm back‑plane connector is fully engaged. Restore power supply, download application program and configuration parameters, verify system logic function.
Usage Notes Take anti‑static protection measures during handling. Back‑up program and configuration data before hardware replacement. Do not scratch conformal coating. Hot‑plug operation under powered state is strictly forbidden.
