ABB UFC933A102 (3BHE048062R0102) Product Brief Specification
Electrical Input & Output

Power Input: 24VDC (±20% tolerance), max power consumption ≤10.5W

Signal Input: Configurable 4-20mA current / 0-10V voltage analog signals and multi-channel digital switching inputs

Signal Output: Analog output for excitation adjustment and digital relay output for peripheral control

Communication: Built-in RS485 and Ethernet ports, supporting Modbus RTU/TCP and PROFIBUS DP protocols

Isolation Performance: 2500VAC dielectric isolation for anti-interference capability

Wiring Mode

Supports dual wiring methods: front screw terminal hard wiring for on-site sensor and actuator connection, and backplane plug-in wiring for integrated cabinet installation. The backplane design realizes one-step power and bus connection; shielded cables are recommended for analog signal wiring to enhance anti-interference ability.

Compatibility & Accessories

Standard matching accessories include guide rails, insulating baffles, dedicated terminals and backplane adapter plates. It supports original ABB accessories and certified third-party compatible accessories for system upgrading and transformation.

Application Scenarios

Mainly used for excitation control of synchronous generators in thermal power, hydropower and gas turbine power plants. Widely applied to high-power inverter and motor variable-frequency control systems in metallurgy, mining and cement industries. Also applicable to signal processing and logic control of DCS automation systems in chemical and papermaking industries.

Product Advantages

Equipped with high-speed 32-bit processing chip for precise excitation closed-loop control. Adopts standard plug-in structure for fast installation and replacement, reducing maintenance downtime. Built-in overvoltage and overcurrent protection ensures stable operation under complex industrial conditions. Features seamless compatibility with original ABB DCS and excitation systems. Fully compliant with IEC61131 international industrial control standards with high operational reliability.
