1. Basic Overview

Model: UFC921A101 (functional model)


Order number: 3BHE024855R0101 (ABB official material number)


Usage: Industrial automation control module, typically used in ABB AC 800M or Freelance 800F systems as an I/O module or communication module.


2. Main functions

May be used for digital input/output (DI/DO) or analog signal processing (AI/AO).


Supports industrial communication protocols such as Profibus DP, Modbus, Ethernet/IP.


Suitable for DCS (Distributed Control System) or PLC (Programmable Logic Control) applications.


3. Technical parameters (to be confirmed in the manual)

Working voltage: 24V DC or 110-240V AC (depending on the specific model)


I/O points: may be 8/16/32 channels (please refer to the specification sheet)


Communication interface: may support RS485, Ethernet, or fiber optic


Environmental adaptability: The working temperature is usually between -20 ° C and+60 ° C


4. Compatibility and Substitution

Original factory replacement: It is recommended to purchase through ABB official or authorized agents to ensure firmware compatibility.


Alternative models: There may be slight differences between different versions (such as UFC921A102), and technical documentation needs to be checked.


Second hand/refurbished market: Some industrial automation spare parts suppliers may offer tested second-hand modules.


5. Common faults and troubleshooting

Power issue: Check if the power supply is working properly (if the LED status light is on).


Communication malfunction:


Check if the Profibus/Modbus wiring is correct.


Confirm whether the DIP switch or jumper settings match the network configuration.


I/O signal abnormality:


Check if the terminal wiring is loose or short circuited.


Use a multimeter or oscilloscope to check if the signal is normal.
