Analog I/O Expansion
Modules
The E300 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
• Vo
