expansion module (encoder wire).
To avoid fluctuating analog values when using these expansion modules, take the following
To avoid fluctuating analog values when using these expansion modules, take the following
measures:
•
•
Use only shielded encoder wires.
•
Shorten the encoder wire as much a possible. The encoder wire must not be more than
10 meters long.
•
Clamp the encoder wire on one side only and clamp it only to the FE terminal on the
AM2/AM2 AQ/AM2 RTD expansion module.
•
Connect ground on the encoder supply to the FE terminal on the expansion module.
•
Avoid operating the LOGO! AM2 RTD expansion module with a power supply that is not
grounded (potential-free). If you cannot avoid this, connect the negative output/ground
output on the power supply to the shielding on the resistance thermometer's measuring
wires.

The LOGO! ...R... version includes relay outputs. The potential of the relay contacts is
isolated from the power supply and the inputs.
