Industrial RS485 to TTL Serial Adapter Converter Module Interface Port TTL to RS485 Serial Conversion Module with Power&Digital Isolation Half&Duplex Communication SP3485 UART
SP3485 chip, stable performance, industrial-grade design standards, can simultaneously realize the TTL signal and RS485 signal bidirectional automatic transceiver, convenient and fast, compatible with 3.3V and 5.0V power supply and signal.
Strong anti-interference ability, increase isolation function, effectively improve the stability of the module work, with lightning protection design, can be used in industrial areas and harsh environments.
TTL to 485: 485 is half-duplex communication, the module can realize two-way communication, but not two-way communication at the same time, it must be alternated in turn.
TTL to 422: 422 is full-duplex communication, this module can realize two-way communication of TTL signal and 422 signal at the same time without mutual interference.
On-board TVS, self-recovery fuse, GDT gas discharge tube, digital isolator, DC/DC power isolation.
