dials, and it provides diagnostic status indicators to provide system status at the
panel. The E300 Electronic Overload Relay supports two network protocols:
•
EtherNet/IP
•
DeviceNet
The E300 EtherNet/IP Communication Module has two RJ45 connectors that
function as a switch. You can daisy chain multiple E300 Electronic Overload
Relays with Ethernet cable, and the module supports a Device Level Ring (DLR).
Optional Add-On Modules
Optional Expansion I/O
The E300 Electronic Overload Relay allows you to add more digital and analog
I/O to the system via the E300 Electronic Overload Relay Expansion Bus if the
native I/O count is not sufficient for the application on the base relay. You can
add any combination of up to four Digital I/O Expansion Modules that have four
inputs (120V AC, 240V AC, or 24V DC) and two relay outputs.
You can also add up to four Analog I/O Expansion Modules, which have three
independent universal analog inputs and one isolated analog output. The Analog
I/O Expansion Modules require Control Module firmware v3.000 or higher. The
independent universal analog inputs can accept the following signals:
•
4…20 mA
•
0…20 mA
•
0…10V DC
•
1…5V DC
•
0…5V DC
•
RTD Sensors (Pt 385, Pt 3916, Cu 426, Ni 618, Ni 672, and NiFe 518)
•
Resistance (150
, 750
, 3000
, and 6000
)
The isolated analog output can be programmed to reference a traditional analog
signal (4…20 mA, 0…20 mA, 0…10V DC, 1…5V, or 0…10V) to represent the
following diagnostic values:
•
Average %FLA
•
%TCU
•
Ground Fault Current
•
Current Imbalance
•
Average L-L Voltage
•
Voltage Imbalance
•
Total kW
•
Total kVAR
•
Total kVA
•
Total Power Factor
•
User-defined Value
