Two-channel Isolation Transceiver for RS485

MORNSUN recently announced a two-channel 485 isolation transceiver module TD5(3)22D485H-A series, to assist fast signal response in industries of power grid, industrial control, transportation and instrumentation, etc.


Product advantages are as follows,

1) Data rate up to 120kbps
2) Two-channel isolation, support full-duplex communication mode
3) Automatic Switching, which can help the user save the cost of software compared to the conventional 485 products
4) Internal devices are highly integrated, the size of duplex series TD5(3)22D485H-A is same as the single out series TD5(3)21D485H-A
5) Adopts our fixed input R3 technology(applying an independent oscillator instead of the Royer circuit, integrating internal discrete components), which is better suitable for full dynamic load applications and can increase the communication reliability of products.





      Features:


▶ Integrated high efficiency isolated DC/DC converter

▶ Automatic switch to send and receive 
▶ Three- port isolation: 2.5kVDC
▶ Operating temperature range: -40℃ to +85℃
▶ High baud rate up to 120kbps
▶ The bus is able to support 32 nodes at maximum



▶ ESD protection, complete EMC recommended circuit
