Product Details

ABB 216EA61b is an analogue input processor unit for ABB REG216 generator protection and control system. The analogue input processor unit receives scaled analogue signals from input transformer modules, converts analog signals into high-precision digital data and transmits data via the system bus to the main protection CPU for protection calculation and real-time monitoring. This ABB 216EA61b unit supports multi-channel synchronous sampling of voltage, current and temperature signals in power systems. The power system signal acquisition board adopts electromagnetic signal isolation circuit to suppress interference in harsh substation environments. It has built-in self-diagnostic function to continuously monitor signal channel status and internal hardware, and trigger alarm information when signal loss or circuit fault occurs. It cooperates with other REG216 modules to complete generator overcurrent, overvoltage and other protection functions. Widely applied in thermal power, hydropower generator sets and transformer protection cabinets, it ensures reliable signal sampling for power protection. Rack plug-in structure enables convenient installation and quick spare parts replacement.
