 RS485/422 light-isolated repeater Manual

     E485GA light-isolated repeater is used to achieve the isolation and relay to enlargement of RS485 and RS422 signals. When RS485/422 communication distance is longer than 1.2 km, this repeater is required in order to realize signal amplification and extend communication distance. The products have characteristics such as high-speed, two-way extending, automatically switching the flow of signals and automatically adaptation of baud rate. All their industrial-grade devices are anti-static and anti-lightning, make them work stably in the poor industrial environment.

Technical details:

★ relay range is up to 2 km(9.6Kbps),1km(115.2Kbps)

★ light-isolated voltage: 1000 VDC (up to 3000 VDC, statement required when ordering)

★ communication rate: 0 ~ 500 Kbps Adaptive

★ 64 RS485 transceivers can be linked to bus

★ work way: Two-wire half-duplex (RS485) and four-wire full-duplex (RS422) optional, automatic identification of RS485 signal flows, and zero delay two-way automatic switching

★ slope-limited driver, to minimize electromagnetic interference, and can reduce the reflection caused by the not match of transmission line terminal

★ transmission lines: cross-sectional area is 0.75 mm2 above, the twisted pair with 120 Ohm impedance

★ 600 W built-in anti-lightning protection and 1500 V built-in anti-static protection 

★ external 5 V, 1W DC power supply, the internal DC / DC isolated power supply

★ temperature: -20 ℃ ~ +75 ℃

★ Dimensions: 85 × 55 × 25

★ installation: installation of 35 mm standard rails and the bolt hole

★ Weight: 100 g
