DollaTek Trademark Reg.NO:013726393. Description: 3.3V with a perfectly compatible 5.0V power supply. 3.3V with 5.0V signal perfectly compatible. Operating temperature: -40°C ~ + 85°C. Size: 42.8 mm x 15.2 mm x 0.8 mm. Features: With RXD, the TXD signal lights up. Transmission distance in kilometers. Absolute adopts imported chip, industrial design, strong anti-interference ability, at the same time more effective lightning protection design, 485 can be used in industrial field and field under harsh environment. (Using 850m with 2 x 1.5 cable to do the test, it is recommended to be used within 800m, over 800m, please add additional repeaters). Using half-process hole design, thickness of 0.8mm, can be used easily as a mother mother child, can also be used welding terminals. With standard 2.54 spacer design, convenient your secondary development. With 120 resistance European match, can make short sub R0 can match resistance, proposed short response long distance transport. Support multiple machine communications, allowed to take up to 128 devices on the bus. This module can be hot pluggable, there will be no other phenomenon hotplug signal switch chip 485 to death. Large copper surface, preventing signal interference. Box contents: 1 x DollaTek TTL to RS485 adapter
