ABB 3BHE024855R0102 Processor Board Unit

Module Feature

3BHE024855R0102 is a control system processor board manufactured by ABB.

It is a plug-in module installed inside the ABB automation control cabinet. The board integrates high-performance processor core, system communication interface, memory and diagnostic supervision circuit. It is responsible for logic execution, data exchange with I/O modules and communication with upper SCADA system. Conformal coated PCB provides moisture, dust and corrosive gas resistance, suitable for harsh industrial environment. Widely stocked as maintenance spare for power plant, chemical, oil & gas and process automation DCS cabinet.

Working principle

After power-on, the board loads system firmware and initializes the communication bus.

It exchanges process data with I/O modules in the rack and executes control logic according to the downloaded program. The diagnostic circuit continuously supervises power supply, bus communication and board health. When a fault is detected, the board reports the error code to the engineering station through the system network, enabling remote fault analysis.

Onboard components

High-performance processor core, flash memory, RAM, system bus transceiver, communication interface circuit, diagnostic supervision chip, status LED bank, backplane gold finger connector, conformal coated PCB and protection component.

LED indicators

Front board LEDs indicate power, run, bus communication and fault status.

Hardware self‑diagnosis

Built-in circuit monitors board power supply, bus communication integrity and internal electronic health. Configuration and fault diagnosis are completed by ABB control system engineering software.

Programming software

ABB Control Builder / engineering software, used for program download, communication configuration and fault log review.
