Industrial RS485 to TTL Serial Adapter Converter Module Interface Port TTL to RS485 Serial Conversion Module with Power&Digital Isolation Half&Duplex Communication SP3485 UARTPRODUCT DESCRIPTION
This is a serial module developed by designed for use with conversion between RS485 and TTL, supporting 3.3V and 5V TTL signals. It can be used stably in industrial scenarios.
The TTL side is equipped with overcurrent protection and surge protection. It can ensure stable output of current and voltage, and strong anti-shock ability.
RS485 terminal with overcurrent protection, surge protection, lightning gas discharge protection circuit.
120R termination resistor pad is reserved on the board, which can increase the stability of signal transmission and reduce interference.
Baud rate support range: up to 2Mbps (In practice, the baud rate supported by this module is limited by the baud rate supported by the access devices at both ends, and needs to be adjusted according to the actual situation.)
Two on-board LEDs are used to indicate the sending and receiving status of the circuit signals.
TXD light: white, TTL data transmission indicator, data flow: RS485->TTL
RXD light: white, TTL data receiving indicator, data flow: TTL->RS485
PRODUCT FEATURES
- SP3485 chip, stable performance, industrial-grade design standards, can simultaneously realize the TTL signal and RS485 signal offerirectional 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.
