RS-422/485 Isolated Repeater 485OPDR www.advantech-bb.com PRODUCT FEATURES • Extend data up to 1.2 km (4000 ft.) • 2000V optically isolated data lines • 600W surge suppression • -40 to 80 °C operating temperature • Modbus ASCII/RTU The 485OPDR is an optically isolated RS-422/485 isolated line repeater that SPECIFICATIONS can be used to isolate a piece of equipment from the rest of the network. As RS-422/485 a repeater, it extends the distance of an existing network an additional 1.2 km Connector Terminal Block (4000 ft.) and expands it beyond the typical 32-node limitation. Data signals TDA(-), TDB(+), RDA(-), RDB(+), GND and the power inputs connect to the terminal block. 600W surge suppression Signals RS-422 4-wire, RS-485 2-wire and 4-wire ensures that the connected equipment is protected even in the harshest of Protected GND on Isolated Side environments. 2-wire RS-485, 4-wire RS-485 and RS-422 are supported. The ISOLATION repeater operates on externally sourced 10 to 30 VDC power. The enclosure has Method Optical a DIN rail mount that is designed to fit easily on a standard 35mm rail.
