#RS422 OPTICAL ISOLATOR SERIAL#

If you need to isolate all communication wires please see our 8-wire optical isolator. ULI-234TCH - RS-422/485 Isolated Repeator, high speed, DIN Rail.

#RS422 OPTICAL ISOLATOR SERIAL#

This is a 3-wire isolator which means that it protects the TX, RX and GND communication wires. RS-485/RS422 Isolated Repeater provides optical isolation protection for data communication between two serial devices, which can effectively avoid damage. An added benefit is that you are able to add another 32 nodes to your RS-485 network and join 2 and 4 wire systems. By configuring one side as RS-422 and the other as RS-485, the models can act as a converter to allow your four wires RS-422 equipment to talk to a 2-wire RS-485 device. In addition to offering 2 KV isolation on the data lines, it can be used to extend your RS-422/485 circuit an additional 4,000 feet, doubling the range. The optical repeaters/isolators add 4,000 feet (1.2km) and another 32 nodes to an RS-485 data circuit. The port powered feature of this isolator means that you do not need to connect an external power supply to the unit, it gets its power from the RS232 port, it can do this effectively without interfering with the data communication. Model 485OP is an optically isolated RS- 422/485 signal repeater. One isolator at each end of your communication wire is recommended if the communication distance is longer than 100 feet, however the recommended distance depends on the amount of static electricity in the surrounding environment. The isolator is easy to connect, simply connect it with the DB9 connectors between your communication wire and your device. The RS-232 side of the converter derives its power from the DTR. The RS-422/485 port has a 6 position terminal block. The RS-232 port has a female DB9 connector with Pin 3 (TD), Pin 2 (RD), and Pin 5 (Ground) passed through. It effectively protects your RS232 devices for up to with 1500V constant voltage, 600W surge protection and 15KV ESD static protection. It also provides 1500 Volts RMS optical isolation of the data lines and ground between the RS-232 and RS-422/485 signals. If you need to effectively protect your RS232 ports and devices against high-voltage spikes, surges, ground-loops and other damaging voltages then this optical isolator is what you need.
