Isolate your RS-232/422/485 equipment from damaging ground loops, spikes and surges

description

    Model 485OPB 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. A 12VDC power supply is required.

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 creepage and air clearance requirements of IEC 601-1. Model 9SPOP2 is a port powered two-channel isolator with a 2500V protection level. Model 9POP4 offers 4 channels of isolation and requires a single external 12 VDC power supply to power both sides, ideal for the low powered ports on laptops and newer PCs.
