The features of the
isolatedtransceiver module,
which integrates transceiver chip, isolation chip
andDC/DC integrated
isolated power - supply interface, are as
follows:
High - voltage Isolation: It usually has a high
- voltage isolation capability, such as
2.5kVRMS signal isolation,
which can effectively suppress noise interference and
prevent the influence of high - voltage on the
circuit, ensuring the stability and reliability of
signal transmission.
Integrated Power Isolation: Integrated with a
DC - DC converter, there is no need for an external
isolated power - supply module, which simplifies the
circuit design and reduces the volume of
thecircuit board.
It can provide isolated power supply for the
bus side, and some can output3.3V
or 5V, with options of 3.3V or 5V power
supply voltage.
High - speedData
Transmission: It can support high -
speed data transmission, with some models having a
maximum communication rate of up to *6Mbps, which is
suitable for high - speed data acquisition scenarios,
and also meets relevant standards, such as ISO
***2:***7(E).
Bus Protection: It has strong bus protection
capabilities, including ±*5kVESD
protection
(HBM) to prevent
electrostatic damage, as well as short - circuit and
over - heat protection functions. The
current - limiting driver can avoid short - circuit
or excessivepower
consumption, and the thermal shutdown
function can protect the chip from damage under high
- temperature conditions.
High Common - mode Transient Immunity: It has a
high common - mode transient immunity, such as
±**0kV/μs (typical value),
which can ensure uninterrupted communication in the
case of large common - mode transients, and is
suitable for harsh industrial environments.
Multiple Protocols Support: It supports
multiple communication protocols, such
asRS - **5 (half -
duplex/full - duplex) and RS - **2, which can be
applied to different industrial communication
scenarios, such as Modbus RTU and Profibus DP
communication in PLC.
WideTemperature

temperature range, generally ranging from - *0°C to +
*5°C or even - *0°C to **5°C, meeting the
requirements of industrial - grade applications, and
can work stably in different environmental
temperatures.
Small Package: It often adopts a small - size
package, such asSOIC - *0,
LGA*6 and other packages, which is suitable for
surface - mount technology, savesPCB
board space, and is convenient for
circuit design and production.
Low Power Consumption: It has a low - power OFF
mode, with a typical value of <1μA, which can
reduce thepower consumption
of the system and is conducive to energy -
saving and environmental protection, especially for
some battery - powered devices.
Ideal Passive Operation: It has an ideal
passive operation mode for theCAN
bus (power - off), which can ensure the
normal operation of the bus under the condition of
power - off and avoid affecting the communication of
other devices on the bus.

data transmission rate, with a maximum data bit
rate of *****0bps, which can meet the requirements of
high - speed data transmission in various application
scenarios.
Bus Protection: It has built - in 4.7K pull -
up and pull - down resistors, and hasESD
protection functions, with contact ±4kV
and air ±8kV. It can protect the bus
fromelectrostatic damage
and other interferences, and improve the reliability
of the communication bus.
Multi - node Connection: The bus driving
ability can support at least *2 nodes, which is
convenient for building a multi - node communication
network and reducing the complexity of wiring.
WideTemperature

which is suitable for surface - mount technology,
savesPCB board space, and
is convenient for circuit integration.
ExcellentEMC
Performance: The electromagnetic radiation EMI
is extremely low, and the electromagnetic anti -
interference ability is extremely high, which can
ensure stable communication in a complex
electromagnetic environment.
