TTL to RS485 Module with Hardware Automatic Flow Control and Terminal Blocks
Product Features
This module fully incorporates lightning protection and anti-interference design for RS485 buses, offering high EMC (Electromagnetic Compatibility) and EMI (Electromagnetic Immunity) performance. For long-distance outdoor transmission, connecting the module’s “Earth Ground” terminal to earth provides excellent anti-interference and lightning protection, ensuring greater safety for the RS485 bus. For short-distance indoor transmission, grounding is optional.
Standard 2.54-pitch pin headers facilitate secondary development.
Features a 120-ohm matching resistor; shorting R0 enables the resistor (recommended for long-distance transmission).
Supports multi-device communication, with at least 40 nodes connectable on the same network.
Supports hot-swapping without signal latch-up issues.
Anti-interference routing and copper coating prevent signal disruption.
Equipped with wiring terminals and silicone wires for ease of use.
Includes RXD and TXD signal indicators for clear monitoring of transmission and reception status.
Delivers high EMC and EMI performance.
Product Parameters
Wide voltage supply range (3.0V–30V), with an absolute maximum voltage of 33V (recommended operation within 30V). Minimum operating voltage must be above 2.8V.
Compatible with both 3.3V and 5.0V signals, ensuring seamless module matching.
Utilizes original chips and industrial-grade design for strong anti-interference capability.
