The DL485-IB2
DL-485-IB2 systems transmit serial IB2-bus signals with data rates up to 3 MBit/s via optical fibers.
They replace/extend equivalent RS485 two-tire connections.
Two power inputs allow a redundant voltage supply.
Possible failures are displayed by an integrated relay and a fault LED.
DL-485-IB2-2X forward RS-485 signals to two optical ports.
