PRODUCT PROFILE
Allen-Bradleys E1 Plus electronic overload
relays are the industrys first modular self-
powered devices. Through the use of
optional side-mount accessory modules,
functionality of the E1 Plus overload relays
can be cost effectively expanded and machine
operation and protection enhanced.
ADVANTAGES:
COMPACT
direct mounting to the left side
of the 193-EE and 592-EE E1 Plus overload
relays, only 18mm is added to the width
SIMPLIFIED CONTROL
the side-mount
modules electronically interface with the
E1 Plus overload relay so that all control
circuit connections are made at the E1
Plus overload relay terminals
FLEXIBILITY
the modular design of the E1
Plus overload relays allows for expanded
functionality in only those applications
where it is required

ESSENTIAL COMPONENTS.
EXCEPTIONAL VALUE.
TAKE THE FIRST STEP TO INTELLIGENT MOTOR CONTROL
Seamless deployment of motor starters onto the Integrated Architecture is cost effectively
accomplished with the E1 Plus Electronic Overload Relay and the optional DeviceNet Communication Module accessory. Streamline processes with enhanced control, protection,
monitoring, and diagnostic capability for improved operating efficiency.

ODVA Conformance Tested
Unconnected Message Manager (UCMM) Support
Get/Set Single Attribute Explicit Messaging
Autobaud Network Rate Detection
INTEGRATED I/O
Integrated I/O allow simplification of the network architecture,
providing local connection of motor starter related inputs and
outputs.
2 Inputs 24 Vdc rated, module supplied
1 Output B300 rated
STATUS INDICATORS
Network Status: Green/red LED indicates the status of the
network connection
OUT A: Amber LED that illuminates when the output contacts
are commanded closed
IN 1 and 2: Amber LEDs illuminate when the user-connected
device contact actuates
OPERATIONAL AND DIAGNOSTIC DATA
The DeviceNet module allows access to the following
information, allowing continual monitoring of machine
performance:
Average Motor Current (as a percentage of motor
rated current)
Percentage of Thermal Capacity Usage
Device Status
Trip and Warning Identification
Trip History (record of five most recent trips)
EXPANDED PROTECTION FUNCTIONS
The added protective functions provided by the DeviceNet
module increase the protection of motor and load. Additionally,
warning functions allow operations personnel to take action
when motor performance parameters exceed permissive limits
so that downtime can be avoided.
Overload Warning: By monitoring the percentage of thermal
capacity utilization (TCU) signal of the E1 Plus overload relay,
the DeviceNet module offers a setting range of 0100% TCU.
Jam Protection: A quick response in taking a motor off-line in
the event of a mechanical jam reduces the potential for damage
to the motor and the power transmission components. Trip
adjustments include a trip setting adjustable from 150600%
FLA and a trip delay time with a range of 0.125.0 seconds. A
separate warning setting is adjustable from 100600% FLA.
Underload Warning: A sudden reduction in motor operating
current can signal an abnormal condition such as pump
cavitation or drive belt breakage. The underload warning
function offers a setting range of 30100% FLA.
