BỘ KHUẾCH ĐẠI TÍN HIỆU KCD2-SR-2 – SWITCH AMPLIFIER KCD2-SR-2
TÍNH NĂNG NỔI BẬT
- Bộ điều hòa tín hiệu này cung cấp sự cách ly điện giữa các mạch trường và mạch điều khiển.
- Nguồn cung cấp 24 V DC (Đường ray điện)
- Thiết bị chuyển tín hiệu kỹ thuật số (cảm biến NAMUR hoặc tiếp điểm khô) từ hiện trường đến hệ thống điều khiển.
- Cảm biến tiệm cận hoặc tiếp điểm cơ điều khiển tải phía điều khiển cho đầu ra tiếp điểm rơ le. Đầu ra thiết bị thay đổi trạng thái khi tín hiệu đầu vào thay đổi trạng thái.
- Có thể sử dụng làm bộ chia tín hiệu (1 đầu vào và 2 đầu ra)
- Thông qua công tắc, chế độ hoạt động có thể được đảo ngược và có thể tắt phát hiện lỗi đường dây. Trong điều kiện sự cố, rơle trở lại trạng thái không có điện và các đèn LED cho biết lỗi theo NAMUR NE 44. Nếu thiết bị được vận hành qua Power Rail, sẽ có thêm thông báo lỗi chung.
- Do thiết kế vỏ nhỏ gọn và tản nhiệt thấp, thiết bị này rất hữu ích để phát hiện vị trí, điểm dừng và chuyển đổi trạng thái trong các ứng dụng quan trọng về không gian.
- Chiều rộng vỏ 12,5 mm
- SIL 2 (SC 3) theo tiêu chuẩn IEC / EN 61508

Thanks for your posting. I would also love to comment that the very first thing you will need to do is determine whether you really need credit improvement. To do that you will need to get your hands on a replica of your credit history. That should not be difficult, because the government makes it necessary that you are allowed to obtain one absolutely free copy of the credit report every year. You just have to request that from the right people today. You can either check out the website for the Federal Trade Commission as well as contact one of the leading credit agencies right away.JJ’s Ducted Gas Heating Repairs and Installation 162 Mitchell Rd, Lilydale VIC 3140 0412 531 821
