Product Overview Chapter 1
diagnostic status indicators to provide system status at the panel. the E300 relay
supports two network protocols:
• EtherNet/IP
• DeviceNet
The E300
EtherNet/IP Communication Module has two RJ45 connectors that
functi
on as a switch. You can daisy chain multiple E300 relays with Ethernet
cable, and the module supports a Device Level Ring (DLR).
Optional Add-On Modules
Optional Expansion I/O
The E300 relay allows you to add more digital and analog I/O to the system via
the E300 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
• R
TD 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:
• Av
erage %FLA
• %TCU
• Ground Fault Current
• Current Imbalance
• Average L-L Voltage
• Voltage Imbalance
• To ta l kW
• To ta l kVA R
• To ta l kVA
• To ta l Pow e r Fa c to r
• User-defined Value
