Industrial Bus TD5(3)31S485-L Series - 1

MORNSUN Low power consumption single RS485 isolated transceiver module, SMD package FEATURES • Ultra-low quiescent current, 8 mA • Small size, SMD package • Integrated high efficient isolated DC-DC converter • High baud rate up to 19200bps • Two-port isolation test voltage (2.5kVDC) • 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 TD331S485L/TD531S485L 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 to2500VDC. The Products are using pick and place SMD technology, thus enabling the use of fully automated processing. 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® Component As the modules internal A / B lines come with its own ESD protection, which generally satisfy most application environments without the need for additional ESD protection devices, as shown in the typical circuit in Figure 1. For harsh and noisy application environments such as motors, high voltage/current switches, lightning and similar however, we recommended that the user protects the module's A / B lines with additional measures and external components such as TVS tube, common mode inductors, Gas discharge tube, shielded twisted pair of wires with the same single...
