CX1100-00x2 connections
This power supply unit is equipped with an I/O interface, which permits connection of the Beckhoff Bus Terminals.
The power is supplied via the upper spring-loaded terminals labelled “24V” and “0V”.
The supply voltage feeds the CX system and supplies a voltage of 24 V DC (-15 %/+20%) to the Bus Terminals via
the K-Bus. The dielectric strength of the power supply unit is 500 V
rms
. Since the K-Bus does no more than pass data
on, a further power supply is necessary for the Bus Terminals. This is provided by means of the power contacts,
which are not connected to the power supply.
The integrated NOVRAM permits storage of process data that is safe against power failure.

LED:
With proper connection of the power supply unit and with power supply turned on, the power LED (PWR) lights up
green. In the case of a short-circuit, it lights up red.
The I/O LEDs display the operation status of the Bus Terminals. Error-free start-up of the configuration is signalled by
the red "I/O ERR" LED being extinguished. If the ”I/O ERR" LED blinks, an error in the area of the terminals is
indicated. The error code can be determined from the frequency and number of blinks.
PE power contacts
The ”PE" power contact must not be used for other potentials.
