Product Introduction:
The TTL485 module can convert between RS485 and TTL levels. The module has an automatic flow control function, enabling automatic switching of the RS485 transmission and reception directions. Users can use the TTL485 module just like a 232 module, without having to consider the transmission direction control. This facilitates user programming and enhances system stability.
The module's design takes into account signal integrity and EMC characteristics, and incorporates multiple protective measures. It can be used in various industrial-grade applications. The module design is simple, the appearance is exquisite, and it is stable and reliable.
Functional Features:
1. The module is powered by 3.3-5V, and the TTL transceiver interface is compatible with both 3.3V and 5.0V levels;
2. The RS485 transceiver direction automatically switches, without requiring user intervention;
3. Industrial-grade design, with stable and reliable performance, and the maximum signal transmission rate up to 500Kbps;
4. Multiple protection measures: ESD protection of ±15KV, 600W dual-channel TVS protection, and instantaneous overcurrent protection;
5. Supports multi-machine communication, allowing up to 128 devices to be connected on the bus;
6. The module supports hot swapping, has strong driving capability, and the maximum transmission distance is 1200 meters;
7. Features a blue power indicator light and green TXD/RXD transceiver indicator lights;
7. Has a 3mm screw hole, allowing for convenient installation of plug-in terminals.
