9 Pins Isolated
- Have problems with your current opto-isolator?
- Need 100% protection, visually confirmed?
- Want immediate plug-in installation?
fully featured optical isolator guarantees you success because:
1. Visually Assured Arrangement
Model VA9 is two separate units that have no metal contact between each other. You can visually confirm complete isolation of signals and ground without a doubt. Only an air gap is between the input and output units.
2. Isolates all 9 pins of DB9 Serial Connection
As this device isolates all 9 pins of the DB9 D-Sub Connector, you can simply plug it into exsisting cables without any jumper wiring to support missing signals. All nine pins at the input are recreated at the output.
