AOM-244 là bộ chuyển đổi RS232/RS485/RS422 sang quang được thiết kế theo chuẩn công nghiệp. Hiện nay, bộ chuyển đổi serial sang quang được sử dụng rất nhiều do giải quyết được bài toán nhiễu điện từ trong truyền thông khi cần truyền dữ liệu ở khoảng cách xa.
Tính năng:
- Efficient lightning-proof function;
- Zero-Delay automatic forwarding;
- End-to-end transparent transmission;
- Supporting three types of interfaces: RS232/485/422;
- Automatic detection of serial port rate, judgment and control of data transmission direction;
- Working wavelength: 850 nm (multi-mode); 1310 nm (single mode);
- Maximum communication rate: 500 Kbps;
- Optional optical interfaces: ST/SC/FC;
- Up to 2 kilometers in multi-mode transmission and up to 20 kilometers in single mode
- transmission.
- Broad voltage inputs: 5-40 VDC or 85-265 VAC
- The interface supports 1500W surge protection and 15KV ESD protection
- External power supply
