TTL to RS485 Level Serial UART Module
TTL to RS485 module (มีสต็อกสินค้าในประเทศไทยพร้อมจัดส่ง)
Module highlights:
(1) 3.3V and 5.0V power perfect compatibility
(2) 3.3V and 5.0V signal perfect compatibility
(3) the absolute adopts imported chip industrial design strong anti-interference ability at the same time adopt more effective lightning protection design 485 can be used in industrial field and field under the harsh environment the working temperature of 40 to + 85 the transmission distance of km (with 850 m 2 * 1.5 cable testing suggest use within 800 meters more than 800 meters please add repeater)
(4) the half hole process design plate thickness 0.8mm can be easily as composite plate can also be used for welding terminal
(5) has the RXD TXD signal indicator lights send and receive status panoramic view
The module features:
(1)This module fully considered485BusLightning protection designAnti interference Design When the long-distance transmission in the field the Earth of the module is connected to the earth which can play a very good role in anti interference and lightning protection.485Bus is more secure; indoor short distance transmission can not access the earth.
(2) with a standard2.54Spacing design to facilitate your two development
(3Have 120Ou matching resistance short connectR0Can match the resistance long distance transmission is recommended.
(4Support multi machine communication allowing access to the most 128A device on the bus
(5This module can be hot plug no other 485Chip hot swap signal plug phenomenon
(6Large area laying copper preventing signal interference
