485OP Optically Isolated RS-422/485 Repeater

FEATURES

Model 485OP is an RS-422/485 signal repeater with 2 kV optical isolation on data lines and terminal blocks for RS-422, RS-485 2 or 4-wire modes. It extends RS-422/485 an additional 1.2 km to double the communication range. Another benefit is the ability to add another 32 nodes to an RS-485 network and join 2 and 4 wire systems. Its compact design fits almost anywhere. Wiring schematic on the label eliminates guesswork. 12 Vdc PSU is required and included with USA, EU, UK, AU, UP and CN blades.
