ABB KS D211 A101 3BHE024313R0101 Input Coupling Unit
KS D211 A101 3BHE024313R0101 is an Input Coupling Unit in the excitation system of ABB UNITOL series generators, which belongs to the signal interface board inside the excitation regulator cabinet. KS D211 A101 3BHE024313R0101 is responsible for electrically isolating, signal conditioning, and impedance matching various analog and switch signals (such as PT/CT voltage and current, speed signals, temperature, circuit breaker auxiliary contacts, etc.) on the field side of the excitation system, coupling and transmitting them to the excitation regulation controller motherboard, while blocking surges, common mode interference, and ground loop impact on the controller on the field side.
