DC 9V-36V RS-485 Repeater Repeater Industrial Grade RS485 Repeater Amplifier Isolated Distance Extender

Description

• INDUSTRIAL GADE DESIGNED: The RS485 Repeater has taken industrial grade design, which communication is completely isolated, with stable and performance, and transmission rate can be up to 500Kbps.
• ELECTRICAL ISOLATION: This Amplifier has built-in a high quality DC/DC isolated power supply module, help to realize electrical isolation between ports.
• LONG DISTANCE COMMUNICATION: The RS485 Repeater supports multi-machine communication, can connect up to 128 nodes, and transmission distance is up to 1200 meters.
• AUTOMATIC PRECISE CONTROL: This Repeater is designed with data automatic control technology, can automatically distinguish and control data transmission direction.
• MULTIPLE PROTECTIONS: The RS485 Repeater Amplifier has taken many protective measures, for example, positive and negative 15KV ESD protection, 600W channel TVS protection, 2.5KV communication isolation.

Wiring Note:
1. 485 communication wires must be shielded twisted pair. It is better to have multi-strand for spare, and the total length is not more than 1,200 meters.
2. Wires should be as far as possible away from high-voltage wires, do not parallel with the power cord and cannot be bundled together.
3.485 bus must behand-hand bus structure, and must not be star connection and fork connection.
4. 485 repeater must be used when there is more than 30 controllers or wire is longer than 500 meters.
5. AC power supply equipment and case must be grounded well.
6. Connect GND of all 485 devices with shielded cable.
7. Connect 120 ohm terminal resistor in parallel to 485+(A) and 485-(B) of the last 485 device.



Package Includes:
1 x RS-485 Repeater
