Fiber optic cable connectors RX / TX
X11: Fiber optic reception interface (RX)
X10: Fiber optic transmission interface (TX)
Data is transmitted in 32Mbit Flex mode. ibaPDA requires a fiber optic card of the
ibaFOB-D family to receive and transmit data.
The fiber optic ports and transmitters are the physical base for a simple send-and-receive
connection to an ibaFOB card. The ports are designed for cables with 62.5/125
µ
m multi-
mode fibers and ST couplings which are available at iba too.
7.3.2
Power supply
The device requires an external DC 24 V ±10% power supply (unregulated) and should
be operated at a maximum of 0.4 A. The operating voltage should be run through the
provided 2-pin Phoenix threaded coupling connector. If desired, you can order DIN rails
or plug-in power supply units from iba.
