Embedded I/O Module
Before You Begin
The CompactLogix™ 5370 L1, series B, controller redesign occurred to provide
an option to use one external power supply for system power and field side power.
There are differences between the CompactLogix 5370 L1, series A and B,
controllers, which are detailed throughout the sections of this manual.
Consider the following before installing a CompactLogix 5370 L1 controller:
ATT EN TI ON : If this equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment can be impaired.
• The control system includes the controller, an embedded power supply,
and embedded I/O points.
• The embedded power supply for the series A L16ER, L18ER or L18ERM
controller is a 24V DC nominal, non-isolated power supply with an input
range of 10…28.8V DC. You wire the embedded power supply via a
removable connector.
• The embedded power supply for the series B L16ER, L18ER, L18ERM
and series A L19ER controller is a 24V DC nominal, isolated
power supply with an input range of 10…28.8V DC. You wire the
embedded power supply via a removable connector.
16 Rockwell Automation Publication 1769-UM021G-EN-P - October 2015
Install the CompactLogix 5370 L1 Controller Chapter 1
IMPORTANT
IMPORTANT
You must use a dedicated external Class 2/SELV-approved power
supply to provide power to the system, according to needs of the
application, and within the operating voltage range of the controller
for only series A L16ER, L18ER, and L18ERM controllers.
The external power supply that provides power to the embedded
power supply of the controller cannot be used to provide power to any
other components or devices in the application for only series A L16ER,
L18ER, and L18ERM controllers.
• A second, fused external power supply must be used to provide power to
other components for only series A L16ER, L18ER, and L18ERM
controllers (see Appendix
C).
• Power for other components can be provided from the external power
supply that is used to provide power to the system for only series B L16ER,
L18ER, L18ERM Controllers, and series A L19ER Controllers.
• The controller has 16 embedded digital input points and 16 embedded
digital output points. You wire the input and output points via a removable
connector.
• The controller supports the use of a limited number of
1734 POINT I/O
modules on the POINTBus backplane as local
expansion modules.
You must use the latest series and firmware revision for all 1734
POINT I/O™ modules in the local expansion slots to make sure that your
application operates as expected. Use of an older firmware revision
renders the entire 1734 bus inoperable.
The following table lists local expansion module support by controller
catalog number.

Installation Summary
A 1784-SD2 SD card with 2 GB of memory storage, or more 1784-SD1
SD cards, are also available if you need extra memory.
The life expectancy of nonvolatile media is dependent on the number
of write cycles that are performed. Nonvolatile media use a wear
leveling technique or technology for prolonging the service life, but
avoid frequent writes.
Avoid frequent writes when logging data. We recommend that you log
data to a buffer in the memory of your controller and limit the number
of times data is written to removable media.
