Rockwell Automation 1760-xxxx Pico Controller User Manual - Manual (Page 17)

Publication 1760-UM001D-EN-P - September 2005
System Overview 1-5
Expansion modules connect directly to the Pico controller as shown
below.
ATTENTION
Electrical isolation is provided between the Pico
controller and the expansion module as follows:
• Basic Isolation: 400V ac (+10%) (1)
• Reinforced Isolation 240V ac (+10%) (2)
The controller and expansion units may be
destroyed if the potential between them exceeds the
Basic Isolation value provided. This may cause your
entire system or machine to malfunction.
(1) Basic Insulation - An insulation system which provides a minimal level of protection against electric shock up to
a stated voltage level. Refer to EN 61131-2 for additional information.
(2) Reinforced Insulation - An insulation system comprised of basic and supplemental insulation. This provides
protection against electric shock up to a stated voltage level and is tolerant of a single fault. Refer to EN
61131-2 for additional information.
TIP
The Pico controller and the expansion module can
be of different voltage types.
