None
LOGO! AM2 AQ 24 V DC None 2 analog
0 ... 10 V DC or
0/4...20mA
5)
1)
Different phases are not allowed within the inputs.
2)
0 ... 10 V, 0/4 ... 20 mA can be connected optionally.
3)
Digital inputs can be operated either with P or with N action.
4)
Two groups consisting of 4 inputs each. Each input within a group must be connected to the same
phase. It is possible to interconnect groups with a different phase.
5)
0 ... 10 V, 0/4 ... 20 mA can be connected optionally. The 0/4 ... 20 mA current output is only
possible with the LOGO! 0BA6 Base Module.
6)
Sensors supported by the LOGO! AM2 RTD module are the PT100 and PT1000 sensors with a
default temperature coefficient α of 0.003850.
