8mA Quiescent Current, Compact Size RS485 Isolated Transceiver Modules- TDx31S485-L, TDx21D485-L series


MORNSUN launched low power consumption, high reliability, small size RS485 isolated transceiver modules, TDx31S485-L and TDx21D485-L series. The quiescent current is as low as 8mA, which are targeted to meet the requirements of coal mines, instruments applications. Besides, the low power consumption makes the series ideal for battery powered applications such as the positioning system for miners, and can improve the anti-interference and reliability of the system.



Applications:
Widely used in the applications of coal mines, instruments, industrial control, power grid.
●  A typical block diagram: Positioning system for miners.




Applications:



Features:
● Low power consumption, ultra-low quiescent current, 8 mA
