Model 485OP optically isolates and protects equipment and also acts as a signal repeater to extend the range of RS-422/485 data lines another 4,000 feet (1,200m). On RS-485 circuits, it allows more than 32 nodes to be used. It works on 2-wire or 4-wire systems. It can also join 4-wire RS-422 with 2-wire RS-485 systems, simplifying the job and saving the cost of another converter.
Model 232SPHI4 has 4000 volts of isolation - twice the rating of most isolators - to protect RS-232 equipment from lightning strikes, accidental high voltage shorts and ground loops. It meets the creep age and air clearance requirements of IEC 601-1. Model 485OPIN is an open card isolator with surge protection.
