Multiservice platform PCM30U-OCH

It is used primarily in HV power networks, where it is necessary to provide highly reliable transmission of individual messages and commands within the transmission system to all necessary nodes. In addition to relaying protection commands, it is advisable to combine other communications into one device. The modular multiservice platform PCM30U-OCH allows you to flexibly assemble different interfaces and transfer protocols into one universal device.
