III. Working Principle

The core working logic of ABB 3BHE023126R0010 follows the sequence of "Signal Access - Power Supply Guarantee - Signal Processing - Command Transmission - Status Monitoring - Diagnostic Feedback". The specific workflow is as follows:

Signal Access and Power Supply Guarantee: Analog or digital signals output by front-end industrial equipment such as sensors and actuators are connected to the product interface through dedicated terminals. The product provides standard working power for itself and front-end peripherals requiring power supply (such as two-wire sensors) through its built-in stable power supply circuit. Meanwhile, it ensures the safety and stability of the power supply circuit through overcurrent and overvoltage protection mechanisms.
Signal Processing and Conditioning: The accessed signals first pass through the internal filter circuit to remove electromagnetic interference and noise in the industrial site, and then are amplified, linearized, or format-converted through the signal conditioning circuit, converting non-standard signals into standard signals recognizable by the controller. Electrical isolation between input signals and backend processing circuits is achieved through isolation circuits to prevent interference signals from affecting processing accuracy and system safety.
Command Interaction and Transmission: The processed signals are transmitted to the ABB controller through the standard communication bus, providing accurate data support for the controller's decision-making and analysis. At the same time, it receives control commands issued by the controller, parses them through the internal logic circuit, converts them into signals executable by terminal equipment, and transmits them to the corresponding actuators to achieve precise control of industrial equipment.
Status Monitoring and Diagnostic Feedback: The product real-time monitors its own power supply voltage, internal circuit working status, on-off status of the signal transmission link, and connection status of front-end/backend equipment. When abnormalities such as signal overrange, circuit failure, loose connection, overheating, or overcurrent are detected, it immediately activates the diagnostic mechanism, generates detailed fault codes including fault location and fault type, and feeds them back to the control system through the communication link. At the same time, it triggers local alarm indicators (power alarm, signal alarm, fault alarm) to remind maintenance personnel to handle the problem in a timely manner.

IV. Common Troubleshooting

Fault Phenomenon	Possible Causes	Troubleshooting and Solutions
Power indicator not lit, product unresponsive	Abnormal power supply (power failure, voltage out of ±10% range), loose or reversed polarity of power terminal wiring, poor connection between product and terminal unit/controller, internal power circuit failure	Use a multimeter to measure the voltage at the power terminals to ensure it meets the 24V DC±10% requirement; check if the power terminal wiring is firm and verify the correctness of polarity connection; inspect the connection interface between the product and the terminal unit/controller to ensure it is properly seated and firm, re-plug to confirm reliable connection; if the above checks are all normal but the product remains unresponsive, internal power circuit failure may be the cause—contact ABB authorized after-sales service for repair or replacement.

Abnormal signal or no signal in specific channels	Loose or broken wiring of the channel, failure of sensors/actuators corresponding to the channel, internal circuit damage of the channel, incorrect calibration parameters of the channel	Re-tighten the signal wiring of the channel and check for broken cables; connect the sensors/actuators corresponding to the channel to other normal channels for testing to determine if there is equipment failure; repair or replace faulty equipment; verify the calibration parameters of the channel and re-calibrate and save the parameters; if the above checks are all normal, internal circuit damage of the channel may be the cause—contact ABB authorized after-sales service for repair.
