- OPTICAL COMMUNICATION
-
Optical isolation adapters, utilize fiber optic cables for the digital communication, which enables extremely reliable communication even in noisy environments such as in factories and for long-distance control. By using optical fibers, they are electrically isolated, so safe operation is possible even in power supply configurations with potential differences.
Application Control of high voltage power supplies via LAN, USB, RS-232C, RS-485, or GPIB. Connection Using fiber optical cables, the adapter for each interface is connected to CO-HV units. With the dedicated control cable, the CO-HV units are connected to a high-voltage power supply AU series. Number of unit Up to 32 pairs with CO-HV unit and high voltage power supply are available. With GPIB, by setting the address, you can connect a maximum of 448 high-voltage power supply units (14 addresses × 32 units). Features The communication system is well suited for such situations where there is a distance between the computer and the high voltage power supply or noisy environments. Also, it is especially ideal for use in combination with DC power supplies. The standard cable length is two meters, and it can be optionally extended up to 40 meters. Example of communication
