SOYAL AR-485REP-V3 Multiple Isolated RS4485 Repeater

SOYAL AR-485REP-V3 Multiple Isolated RS4485 RepeaterProduct 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.
