Technical Specifications Industrial communication physical interface, back‑plane bus data interface. Auxiliary power 24 V DC, typical power consumption 5.3 W. Operating temperature ‑10 ℃ to +55 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Conformal coated circuit board.
Functional Features Processes industrial communication protocol stack. Transmits local equipment operating data and fault codes to upper host system. Receives remote control commands and parameter modification instructions. On‑board LED indicates communication link and module operating status. Built‑in hardware self‑diagnosis detects communication link abnormality. Conformal coating provides moisture‑proof and dust‑proof protection.
Application Scenarios Communication spare‑part for ABB power control and DCS systems. Used for data interconnection between on‑site equipment and remote monitoring platform in energy and chemical industry.
Performance Parameters Stable real‑time data transmission under industrial electromagnetic interference environment. Fast fault identification for communication link interruption. Reliable bidirectional data interaction performance.
Material Composition Multilayer glass‑fiber epoxy printed circuit board. Protocol processing chip, signal isolation assemblies. Conformal protective coating. Back‑plane plug‑in connectors and external communication wiring terminals.
Structural Characteristics Plug‑in circuit board adapting to control rack slot. Board edge equipped with back‑plane bus connector and external communication terminals. Reserved mechanical fixing holes. Weight approximately 0.61 kilogram.
Working Principle After power‑on, board completes hardware self‑test and communication protocol initialization. It exchanges internal data with main processor board via back‑plane bus. Protocol conversion is performed for data packets. Signal sending and receiving are completed through external communication interface. Diagnosis circuit monitors communication link status continuously.
Installation Requirements Disconnect rack auxiliary power before replacement. Insert 3BHE035301R1002 into designated slot and tighten fixing screws. Complete external communication cable wiring. Confirm back‑plane connector is fully engaged. Restore power supply and verify bidirectional data communication function.
