MORNSUN DIP Low power consumption Compact Size RS485 isolated transceiver module TD_D485-L - 1

MORNSUN Low power consumption single RS485 isolated transceiver module FEATURES • Ultra-low quiescent current, 8 mA • Integrated high efficient isolated DC-DC converter • High baud rate up to 19.2kbps • Two-port isolation test voltage(3.0kVDC) • Operating ambient temperature range: -40°C to +85°C • The bus supports maximum 16 nodes • Set isolation and ESD bus protection in one • Used in coal mines, chemical industries request ultra-low power consumption The main function of the TD321D485-L/TD521D485-L series is to convert a logic level signal into isolated RS485 differential level signals. The special integrated IC technology of the RS485 transceiver achieves isolation between the power supply and the signal lines isolation, does RS485communication and protects the bus all in one and the same module. The product's isolated power supply withstands a test voltage of up to 3000VDC. Also, they can easily be embedded in the user's end equipment, to achieve fully functional RS485network connections. The products feature ultra-low power consumption and are guaranteed in coal mines, chemical industry areas with continue operating at low energy consumption.

MORNSUN® Note: Ground shield of twisted wire pair reliably. Recommended components and values: 2) TD521D485-L is for 5V TTL level only (not compatible with 3.3V); TD321D485-L is for 3.3V TTL level only (not compatible with 5V). 3) Pin6 are not drawn. Please leave pin 10 open if unused. 4) We recommend using a shielded twisted pair of wires for the Data transmission line and using same single point earth connection for each of the networks. 5) From the truth table characteristics, it can be derived that the isolated RS-485 transceiver module's CON pin is low to send data and high when...
