GENERAL DESCRIPTION
Single high rate RS485 isolation transceiver module
TD301D485H-E/TD501D485H-E
series
are
RS485
transceiver module with integrated
isolated
power, Signal
isolated chip and the bus protection device.
Product's main function is to convert logic level to
difference level of the 485 agreement, and it implements the
function of signal isolation.Products
is with isolation power. It
can achieve 2500 VDC electrical isolation and have the
function of ESD protection. Product can be easily embedded
user equipment, makes the equipment easily implement
connection of 485 protocol network .
