SOYAL AR-485REP-V3 Multiple Isolated RS4485 Repeater
Product Introduction
Multiple Isolated RS485 Repeater The two sides of the communication and the power supply adopt triple-layer isolation design , which can provide RS485 clean transmission completely isolated from the system power supply
Feature
- 9-24VDC wide input, Triple-Zone DC/DC power isolation, built-in antisurge,
- static electricity, and lightning protection.
- The signal isolation strength of automatic direction detection can reach m3.0KV.
- Fully transparent data transmission; Support communication protocols such as MODBUS RTU and encrypted transmission.
- Industrial-grade RS-485 signal repeater and amplifier distance extender
RS485 wiring precautions
-
485 communication lines must use shielded twisted-pair; all 485 equipment on the lines must be connected to same GND ground.
-
The theoretical length of 485 communication line should not exceed 1000 meters. According to actual experience and on-site environment, it is recommended that the total
length should not exceed 500 meters, 485repeater should be added if it exceeds 500 meters -
The theoretical maximum of devices on the 485 bus should not exceed 64; If it exceeds, a 485 repeater should be added.
-
The 485 bus must be a hand-in-hand bus structure, and resolutely avoid the way of star and bifurcation connection.
-
The 485 wirings should be as far away from interference sources as possible such as high-voltage power supply / electric mains / high-radio frequency signal cables, and not to be bundled together; if it is necessary to run with these cables in parallel, please add EMT conduit tube.
Specification
Green LED (Power) will keep lighting up when powering on. Indicator
- Red/Green LED(Port∣/Port∥) flashing means data is receiving from RS-485 is communicating.
- Red/Green LED (Port∣/Port∥) flashing means data is receiving from RS-485 is communicating
