TTL To RS485 Power Supply Module Long Distance Transmission 3V 5.5V 485 To Serial UART Level Mutual Converter Converter Module Automatic Flow Control Module
Features:
1. Superior Design for Protection & Anti-Interference Design:This ttl to rs485 power supply module features a comprehensive design for protection and anti-interference design for safe outdoor long-distance transmission by connecting the "ground" terminal to the ground. For indoor short-distance transmission, grounding is not required.
2. Standard 2.54 Pin Spacing Design for Easy Secondary Development:With its standard 2.54 pin spacing design, this 485 to serial uart level mutual converter is suitable for your secondary development needs.
3. 120-Ohm Matching Resistor for Long-Distance Transmission:With a built-in 120-ohm matching resistor that can be enabled by shorting R0, this 485 to serial uart level mutual converter is perfect for long-distance transmission.
4. Multi-Machine Communication with Support for up to 128 Devices:This ttl to rs485 power supply module supports multi-machine communication and allows for connection to a maximum of 128 devices on the bus.
5. Hot Swappable & Large Copper Coverage for Minimal Signal Interference:Featuring hot swappable capabilities and large copper coverage, this ttl to rs485 power supply module reduces signal interference and prevents signal jamming during other 485 chip hot-swapping events.
Specification:
Origin: Mainland China
Type: Module
Condition: New
Model Number: TTL to RS485 Signal Converter
Module Highlights:
(1) 3.3V and 5.0V power supply perfectly compatible
(2) 3.3V and 5.0V signals are perfectly compatible
(3) Absolutely using original imported chips, industrial grade design, super anti-interference ability, while using more effective 485design for protection, can be used in industrial sites and field under harsh environment, the working temperature is -40 ℃ to +85 ℃, the transmission distance can reach a thousand meters (with the 850 meters of 2 * 1.5 cable to do the test, it is recommended to use within 800 meters, more than 800 meters please add repeater)
(4) Half-hole process design, board thickness 0.8mm, can easily be used as a daughter board, can also be used as a solder terminal
(5) With RXD and TXD signal indicators, the transmission and receipt status can be seen at a glance
(6) Size: 43*16mm/1.69*0.63in
(7) Net weight: 2g
Note:
1. This transmission module realises the interchange of TTL signals and RS485 signals, but you must know that 485 is a half-duplex communication, this communication method can achieve two-way communication, but not in both directions at the same time, must take turns alternately; that is to say, each end of the communication channel can be the transmitting end or the receiving end, but at the same time, the information can only have One direction of transmission.
2. Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
3. Please allow 1-2cm measuring deviation due to manual measurement.
