Internal current consumption:
from +5 V bus (without en-
coder)typically 210 mA, max. 230 mA
(250 mA in SSI operation)Internal current consumption:
from V+ bus (without encoder)15 ... 20 mAExternal current consumption: 0 ... 2 mA (without load current)
1 A for outputs
Total current consumption for all I/O modules including encoders must not exceed 1.6 A.
PCD2.H32x modules should be plugged onto the base unit wherever possible (not the ex-
pansion housing).
