Use to optically isolate one piece of RS485 equipment from the rest of an RS485 system or one local group of RS485 equipment from another, or it can be used as a repeater to expand an existing RS485 system beyond the standard's 32node limitation. Can also be used to connect equipment meant for a pointtopoint RS422 4wire interface to an RS485 2wire multidrop system in factory automation, building automation, and process automation. They can be mounted using DIN Rail and can withstand operating temperatures of 40 to 176 degrees F (40 to 80 C). FeaturesNIB-DIN Rail Repeaters with Opto-Isolation RS-422-RS-485Isolates one RS485 device from the rest of an RS485 system or one local group of RS485 equipment from another.Connects pointtopoint, RS422 4wire equipment to an RS485 2wire multidrop system.Can be used as a repeater to expand an RS485 system beyond 32 nodes.Operates 2wire halfduplex or 4wire half or fullduplex.Features 12 userselectable data rates up to 460.8 kbps.This compact device links RS422 4wire and RS485 2wire systems while using optical isolation to protect equipment and lines from damaging ground loops.SpecificationsWeight: 0.53 lbs
