DIRECT I/O DATA RATE
over direct inputs and outputs must be set to the same data rate. UR-series IEDs equipped with dual-channel communica-
tions cards apply the same data rate to both channels. Delivery time for direct input and output messages is approximately
0.2 of a power system cycle at 128 kbps and 0.4 of a power system cycle at 64 kbps, per each 'bridge'.

regardless of the physical media of the two communication channels.
The following application examples illustrate the basic concepts for direct input and output configuration. Please refer to the
