Remote IO unit RIO600
The remote inputs/outputs unit RIO600 is designed to expand the digital and analog
inputs/outputs of ABB’s Relion
® protection relays and to provide inputs/outputs for the
substation automation device COM600S using the IEC 61850 Ed.2 communication. The
RIO600 communicates with the protection relays over the Ethernet cable via fast horizontal
GOOSE communication.
Figure 17: Overview of RIO600 connection
The RIO600 AOM4 analog output module has four mA outputs providing mA output signal in
range 0–20mA. These outputs can be used for connection to the analog/digital panel meters.
Operation accuracy of mA output is 0.1% or 0.2mA. There is an option to use a selector switch
to display more than one phase on one panel meter.
