TTL to RS485 Module

Product Parameters:

1. Wide voltage power supply (3.0V~30V), with a limited voltage of 33V. It is recommended to use within 30V, with a minimum voltage higher than 2.8V.

2. Compatible with 3.3V and 5.0V signals, compatible with modules.

3. It has very high EMC and EMI performance.

4. It adopts imported chips with industrial grade design and strong anti-interference ability. At the same time, it adopts a powerful 485 design, which can be used in harsh industrial and outdoor environments. The operating temperature is -40 ° C to+85 ° C, and the transmission distance can reach kilometers (using 850 meters of 2 * 1.5 cable for testing, it is recommended to add a repeater within 800 meters and above 800 meters).

5. Equipped with wiring terminals and silicone wires, it is very convenient to use.

6. Equipped with RXD and TXD signal display, providing a panoramic view of transmission and reception.

Product Fatures:

1. This module is fully designed as a 485 bus protection and anti-interference design, with high EMC and EMI performance. It can be transmitted over long distances on site, and the "grounding" side of the module is grounded, which can play a good role in anti-interference - the interference and protection of the 485 bus are safer; Indoor short distance transmission cannot be grounded.

2. Equipped with 2.54 pitch pins as standard, it is convenient for your secondary development.

3. Equipped with a 120 ohm matching resistor, short circuiting R0 can activate the matching resistor. Short circuiting is recommended for long-distance transmission.

4. Support multi machine communication, and the same network can connect at least 40 nodes.

5. It can be hot swapped and there will be no signal crash.

6. Anti interference wiring and copper path to prevent interference with signals.
