Mô tả

Rơle giám sát để giám sát điện áp 3 pha 280…520 V AC, cửa sổ, với kết nối dây trung tính, điện áp nguồn có thể được lựa chọn thông qua mô-đun nguồn, 1 tiếp điểm chuyển đổi

Ngày càng có nhiều yêu cầu cao hơn về tính an toàn và tính khả dụng của hệ thống - trên tất cả các lĩnh vực. Các quy trình ngày càng trở nên phức tạp hơn, không chỉ trong kỹ thuật cơ khí và công nghiệp hóa chất mà còn trong công nghệ nhà máy và tự động hóa. Nhu cầu về kỹ thuật điện cũng không ngừng tăng lên.

Hoạt động không có lỗi và do đó tiết kiệm chi phí chỉ có thể đạt được thông qua giám sát liên tục các thông số hệ thống và mạng quan trọng. Rơle giám sát điện tử trong sê-ri EMD có sẵn cho nhiều nhiệm vụ giám sát để tránh hậu quả của lỗi hoặc giữ chúng trong giới hạn.

Các trạng thái hoạt động được biểu thị bằng đèn LED màu, các lỗi có thể xảy ra có thể được gửi đến hệ thống điều khiển thông qua tiếp điểm nổi hoặc có thể tắt một phần của hệ thống. Một số phiên bản thiết bị được trang bị độ trễ khởi động và phản hồi để nhanh chóng chịu được các giá trị đo được bên ngoài phạm vi giám sát đã đặt
