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
