Safety-related Analog
Output Module (1755-OF8)
The 1755-OF8 module uses analog outputs to transfer analog values
from the user program into outputs ranging from ±10V DC and
0…20 mA. The relationship between the value in the user program
and the output value is linear and is displayed in this table.
Current Draw
The GuardPLC 2000 controller features several different modules.
These modules and their backplane current draw specifications are
listed in this table.
Connect the power supply, 1755-PB720, to the 24V DC supply
voltage. Refer to the GuardPLC 2000 Power Supply Installation
Instructions, publication
for detailed instructions.

TIP
The GuardPLC 2000 controller can draw up to 30 A. The majority
of this 30 A is used to source inputs and outputs. Only 1 A is
required to operate the CPU module.
