Main features and advantages
16-channel I/O capacity: The UFC921A101 3BHE024855R0101 offers 16 isolated digital input/output channels, allowing it to monitor and control 16 separate field devices—such as limit switches on a conveyor line or solenoid valves in a chemical plant—with a single module. This reduces hardware complexity and simplifies system wiring.
Fast response time: With a response time of less than 1 ms, the module quickly detects changes in input signals, making it ideal for high-speed applications like bottling lines or paper mills, where delays could cause product defects or equipment damage.
Robust isolation and protection: 1500 V RMS channel-to-ground isolation shields the UFC921A101 3BHE024855R0101 from electrical noise and ground loops, ensuring accurate signal detection in noisy environments. Built-in overvoltage and short-circuit protection further safeguard the module and connected equipment.
Wide operating range: The module operates reliably in extreme temperatures (-40°C to 70°C) and high humidity, making it suitable for outdoor power plants, cold storage facilities, and damp environments like water treatment plants. Its conformal coating repels dust and chemicals, extending service life.
Flexible communication: Support for Modbus, Profibus DP, and CANopen protocols allows seamless integration with existing control systems. This flexibility enables the UFC921A101 3BHE024855R0101 to work with both legacy ABB components and modern industrial networks, simplifying system upgrades.
Easy integration: Designed for DIN rail mounting, the UFC921A101 3BHE024855R0101 installs quickly without special tools. It connects directly to ABB’s S800 I/O bus and AC800M controllers, requiring minimal configuration via ABB’s Control Builder software.

Installation and maintenance
Pre-installation preparations: Verify the UFC921A101 3BHE024855R0101 is compatible with your system’s power supply (24 V DC ±10%) and communication network (Modbus, Profibus DP, or CANopen). Mount the module on a 35 mm DIN rail, leaving at least 50 mm of clearance for cooling. Connect the 24 V DC power cable to the input terminals, and link communication cables to the appropriate ports. Check wiring against the module’s pinout diagram to avoid polarity errors. Power on the system and confirm the green status LED is lit.
Maintenance suggestions: Inspect the UFC921A101 3BHE024855R0101 monthly. Wipe dust from its surface with a dry cloth to prevent overheating. Check terminal screws for tightness—loose connections can cause intermittent signal loss. Use the module’s status LEDs to diagnose issues: a steady red LED indicates a fault. If a channel fails, test the connected sensor first; if the sensor is operational, power off the system and reinsert the module to resolve potential backplane connection issues. Store a spare UFC921A101 3BHE024855R0101 in a dry, cool area (10–30°C) for quick replacement during emergencies.
