Profibus Bus Fault LED
Slave Fault LED
For use with PXR 20/25 electronic
trip units (ETUs). The PXR-PCAM
is designed to connect with a
circuit breaker's CAM-PXR link
and expand the communication
capabilities into a slave Profibus
DP interface.
The module also provides limited
discrete I/O, circuit breaker control
capability, and data storage rele-
vant to the breaker. The module
is mounted local to the breaker to
keep the CAM-PXR link limited to
3m maximum
WARNING
Be sure that all distribution
power is off when commission-
ing a PXR-PCAM with a circuit
breaker system. The module can
be powered temporarily via the
USB configuration port or
permanently with the 24 Vdc
power supply input.
IMPORTANT
Download the GSD file for the
PXR-PCAM on the Eaton website.
