• Strong anti-jamming ability, and strong 485 lightning protection design, working temperature is - 40 -85℃.
• With terminal and silicone wire, it is very convenient to use.

Feature: Wide voltage supply (3.0V~30V), limit voltage 33V, recommended to use within 30V, the minimum voltage should be higher than 2.8V. Compatible with 3.3V and 5.0V signals, both can match the module. Excellent EMC and EMI performance. Strong anti-jamming ability, and strong 485 lightning protection design, working temperature is - 40 -85℃ With terminal and silicone wire, it is very convenient to use. With RXD and TXD signal indicators. This module fully considers the lightning protection design and anti-interference design of 485 bus. It has very high EMC (electromagnetic compatibility) and EMI (electromagnetic anti-interference) performance. When long-distance transmission in the field, connecting the "earth" end of the module to the earth can play a very good anti-interference and anti-lightning role, making 485 bus safer; indoor short-distance transmission can not access the earth. With standard 2.54 spacing needle arrangement, it is convenient for your secondary development. With 120 Euro matching resistance, short R0 can make matching resistance possible, and short R0 is recommended for long-distance transmission. Supporting multi-machine communication Package Included: 1 x TTL to R485 Converter Module
