Power supply and current consumption The 8 I/O node requires 12VDC which should be supplied directly
from the Controller PSU or form a remote PSU. Current Consumption - Quiescent State: 100mA, Maximum:
200mA .
햻
Ringnet Communications Connect the ringnet cable to the four terminals 1A to 2B. These terminals are used
for connecting the 8 I/O node onto the ringnet – as illustrated in the following connection diagram and cable type
table.
