Output Duration Timer – This feature allows the E300 output relays to stay in a specified state (On, Off, or Last State) for a specified period of time when the network connection is lost. If the network connection is restored by the same Logix controller or a secondary/backup Logix controller within the specified time period, then the outputs will be controlled by the connecting device. If a network connection is not made, then the output relays will go into a Final Fault state (On or Off).
User Selectable Input Tags – Users now have the option to only read back only 8 programmable data links (40 bytes) compared to the original 156 bytes of information.
Enable/Disable Automatic Device Configuration – Users now have the option to enable or disable Automatic Device Configuration. If a user would rather make and maintain configuration changes using the E300 Diagnostic Station or web server, the user can disable Automatic Device Configuration in their Logix project.

7. Easy Integration Into Logix
Pre-configured operating modes (embedded DeviceLogix programs) allow the Control Station or Diagnostic Station to be used as an operator interface for hand / auto (local / remote) motor control with no ladder logic
The Control Station and Diagnostic Station are operator interface devices that provide buttons for start, stop, control mode, and reset commands. The buttons and corresponding LEDs are controlled via the user selectable Operating Mode (embedded DeviceLogix program). The Operating Mode requires no additional ladder logic in a Logix controller. Simply, add the E300 to the Logix project, select the appropriate Operating Mode for your motor starter application, and use the output tags O.LogicDefinedPt00Data and O.LogicDefinedPt00Data to control the motor remotely with the Logix controller.

Each expansion bus module includes a 20cm piece of expansion bus cable in which the user will daisy chain the modules on to the expansion bus. If 20cm is too short for the application, a 1m expansion bus cable is available as an accessory (catalog number 193-EXP-CBL-1M).
The user turns the rotary dial of the expansion bus to configure the appropriate analog expansion module number (1-4). The expansion bus is a CAN based network which needs terminating resistor at the end of the network. The terminating resistors are incorporated into the analog expansion module and are activated using module numbers (1T-4T).
The analog expansion module is schedule to be part of Release #3.
Expansion Power Supply
Natively, the E300 Electronic Overload Relay can power one digital module and one operator station on its expansion bus when the ambient temperature is below 45ºC. Consult the users manual for specific limitations and restrictions. For applications that involve more than one digital expansion module, any analog expansion module, or are located in ambient temperatures above 45ºC, a supplemental expansion bus power supply is needed. The expansion power supply can supply supplemental power of a fully loaded expansion bus that includes 4 digital expansion modules, 4 analog expansion modules, and one operator station.
There are two types of expansion bus power supplies:
V AC 50/60Hz
24V DC
Each expansion bus power supply includes a 20cm piece of expansion bus cable in which the user will daisy chain the modules on to the expansion bus. If 20cm is too short for the application, a 1m expansion bus cable is available as an accessory (catalog number 193-EXP-CBL-1M).
Both types of expansion power supplies are available today.

The E300 continuously monitors and provides motor performance information. Users can monitor this information with a SCADA system (like FactoryTalk View) to provide alarms and indicate to machine operators poor motor performance.
L1, L2, L3, Average Percent Full Load Amperes (%FLA - Motor current consumption compared to the motor nameplate rating)
Percent Thermal Capacity Utilization (%TCU – The amount of heating capacity used within the motor; 100% equals an Overload Trip)
The E300 provides a lot of useful information when the E300 trips on a trip or warning event. The trip and warning status words provides real-time information for the reason of the trip or warning event which can be displayed in a SCADA system such as FactoryTalk View. This information can be used by maintenance personnel to help trouble shoot the motor issue. Up to five trip and warning events are logged into the trip and warning histories which are stored in non-volatile memory. Maintenance personnel can use the trip and warning history information to see if any trends exist that could indicate any motor system issues.
The E300 also includes a Trip Snapshot in which the following real-time data is recorded into non-volatile memory. This information allows maintenance personnel to see what the power parameters were of the motor at the time of the trip event. This is a great tool to detect which fuse was blown on a phase loss trip.

The E300 provides machine operators preventative diagnostic tools such as:
Time to Trip – provides operators the information needed to decide if a process can be finished before the motor goes into an overload state.
Time to Reset – provides operators the time in which a motor can be restarted after an Overload trip event.
Operational Hours – a preventative maintenance tool to indicate to maintenance staff when a motor has run “x” hours.
Number of Starts – preventative maintenance tool to indicate to maintenance staff when a motor has had “x” starts.
The voltage, power, and energy diagnostic information is part of Release #2. All other diagnostic parameter described above are available today.

17. Reduced Wiring and Installation Costs
E300 Overload Relay modules easily snap together and are secured with locking tabs.
Simplified wiring between E300 Overload Relay and 100-C Contactor
Operator Stations feature a standard mm push button cutout
The E300 was designed to be modular to reduce catalog number SKUs, easy to install, and reduce wiring needed for three component combination starters.
Modular Design
The three main modules of the E300 base relay are easy to install and secure. Users simply put any control module on top of any sensing module and push the bottom latch on the control module to secure it. Users simply put any communication module on top of any control module, and push the top latch on the control module to secure it. All modules have removable terminal blocks for control wiring.
Replacement of any E300 module is made easy too. The user simply removes the terminal blocks for control wiring, unlatch the appropriate module, replaces the affected module, re-latches it, and replaces the control wiring terminal blocks.
Simplified Wiring
The E300 provides an accessory with every 100-C contactor mount sensing module that reduces the control wiring needed for a three piece combination starter as long as the contactor coil voltage matches the E300 control voltage, and the contactor coils are located on the load side of the contactor. The installer simply installs the Coil Adapter into the contactor coil, slides the E300 into the 100-C contactor, adds control power wires to the E300 Electronic Overload Relay, and tightens all of the power and control terminal to have a functional full voltage non-reversing starter. No extra wiring is needed.
Easy Installation
The E300 operator stations easily mount into a standard 22mm push button knock out (just like the 800-F push buttons). Both the Control Station and Diagnostic Station are rated for IP65 (NEMA 4X). The installer does not need to cut a specialized square hole in the enclosure.

18. Flexibility and Functionality
The E300 can be applied to three styles of motor starters
Panel / DIN Rail
100-C IEC Contactors
300/500 NEMA Contactors
The E300 can be applied to three different types of three piece motor starters
- DIN Rail / Panel Mount
- IEC Combination Starters
- NEMA Starters
NOTE: Extra control wiring is not needed when the coil adapter accessory is used with a 100-C contactor mounted E300 Electronic Overload Relay.
