Analog I/O Expansion
Modules The E300 Electronic Overload Relay supports up to four Analog I/O Expansion
Modules on the E300 Expansion Bus. The E300 Analog Expansion Module has
three independent universal inputs and one analog output.
Analog Input Channels
The universal analog inputs can accept the following analog signals:
• Current
– 4…20 mA
– 0…20 mA
• Voltage
– 0…10V DC
– 1…5V DC
– 0…5V DC
• 2-Wire or 3-Wire RTD Sensors
– 100 Ω, 200 Ω, 500 Ω, 1000 Ω Pt 385
– 100 Ω, 200 Ω, 500 Ω, 1000 Ω Pt 3916
– 10 Ω Cu 426
– 100 Ω Ni 618
– 120 Ω Ni 672
– 604Ω NiFe 518
• Resistance
– 0…150 Ω
– 0…750 Ω
– 0…3000 Ω
– 0…6000 Ω (PTC and NTC Sensors)
The analog inputs can report data in four different formats. Table 63 through
Table 66 display the data ranges for all of the available analog input types for the
four available data formats.
