Technical Specifications System internal bus interface, external host communication port, auxiliary DC control power supply. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Conformal coating environmental protection.
Functional Features Exchanges real‑time running data and fault information with local main control board. Completes communication protocol encoding and decoding. Transmits equipment running status, alarm and fault record to upper monitoring host. Receives remote parameter setting and control command from host. Built‑in self‑diagnosis detects communication channel abnormality.
Application Scenarios Spare communication interface board for ABB converter and excitation cabinet. Used for power equipment remote monitoring and spare‑part replacement.
Performance Parameters Stable bidirectional communication data transmission performance. Reliable communication fault diagnosis capability.
Material Composition Multilayer glass‑fiber epoxy printed circuit board. Communication processing chip, system bus peripheral circuit, external communication port assemblies. Multi‑pin plug‑in connectors and metal screw mounting hardware. Conformal protective coating layer.
Structural Characteristics Rectangular circuit‑board structure. Internal system bus connector and external host communication port are arranged on different edges. Reserved screw mounting holes for cabinet internal installation. Internal bus area and external communication area keep layout separation.
Working Principle UFC760BE1142 obtains auxiliary DC working power. It receives real‑time process data and fault information from local main control board via internal bus, packages data into host‑side protocol frame and sends to upper monitoring host. Remote command issued by host is parsed and transmitted to main control board through internal bus.
Installation Requirements Fully insert and lock each plug‑in connector. Connect external host communication cable. Restore power supply, configure communication parameters, verify data exchange between local equipment and upper monitoring host.
