Specification:
Condition: 100% Brand New
Item Type: TTL RS485 Mutual Conversion Module
Material: Aluminum
Wide Voltage Supply: 3.0V~30V
Limit Voltage: 33V, it is recommended to use within 30V, the minimum voltage is higher than 2.8V.
Size: Approx. 52 x 23cm / 20.5 x 9.1in
Features:
1485 bus anti-thunder design and anti-interference design, high EMC (electromagnetic compatibility), EMI (electromagnetic anti-interference) performance, when the long-distance transmission in the field, the module's "connected to the earth" end is connected to the earth, good anti-interference and anti-thunder effect, the 485 bus is more secure; the indoor short-distance transmission can not be connected to the earth. 2With standard 2.54 pitch pin for your secondary development. 3With 120 ohm matching resistor, shorting R0 can enable matching resistor, short circuit is recommended for long distance transmission. 4Support multi-machine communication, at least 40 nodes can be connected to the same network. 5Can be hot plug and unplug without signal embolism. 6Anti-interference type wiring and copper plating to prevent signal interference. 7Compatible with 3.3V and 5.0V signals, can match with the module. 8It adopts imported chips, which can be used in industrial environment and in harsh outdoor environment. The working temperature is -40 C to +85 C, and the transmission distance can reach kilometers (using 850 meters of 2*1.5 cable to test, it is recommended to use within 800 meters, more than 800 meters, please add repeater) 9With terminal block and silicone wire, it is very convenient to use. 10With RXD, TXD signal indicator, the receiving and receiving status is clear.
