3.3V/5V TTL To RS485 Converter Isolation Module TTL-RS485 Converter Board Isolated TTL-RS485 Converter With Auto Reverse Surge Protection - RS1797

Description:

This product through a high-end isolation chip to achieve the TTL, RS485 on both sides of the power and signal perfect isolation, anti-interference ability super. Power is a wide voltage input (3v ~ 5.5v), to achieve the 3.3v system and the 5v system is perfectly compatible.

It has an industrial design, and anti-interference ability, while the use of more powerful 485 lightning design, industrial and field can be used in harsh environments, the working temperature of -40 ° ~ 85 °. Transmission distance of up to kilometers (with 850 meters of 2 * 1.5 cable to do the test, it is recommended to use within 800 meters, more than 800 meters plus repeaters). It uses a half-hole process design, a thickness of 0.8mm, class easy to use as a master, but also welding terminal use.

Specifications:

• Wide Voltage Supply: 3.3V-5V
• Baud Rate: 100-256000bqs

Features:

• The standard 2.54 pitch design is adopted to facilitate your secondary development.
• It has a matching resistance of 120 ohms, short-circuiting RO can enable the matching resistance, and short-circuiting is recommended for long-distance transmission.
• Support multi-machine communication, at least 128 nodes can be connected to the same network.
• Hot-swappable, no signal-blocking phenomenon.
• Anti-interference wiring and copper laying method to prevent signal interference

Package Included:

1 x 3.3V/5V TTL To RS485 Converter Isolation Module TTL-RS485 Converter Board Isolated TTL-RS485 Converter With Auto Reverse Surge Protection
