Power Supply
Connection
The AC 80 is powered by a single or redundant 24 V d.c. (19.2 to 30 V)
supply. The table below gives the current consumption at three different
voltages (without I/O modules).
Power Supply Terminals
The power supply terminals accept wire sizes from 0.2 to 2.5 mm
2
(24 to 14 AWG). The terminal designations are as follows:
Note:
It is recommended that the AC 80 and the I/O devices be
powered from separate supplies.
