Product Overview
The Schneider Electric TM3AI4 is a
Modicon TM3 four-channel analog input expansion module
for compatible M221, M241, M251 and M262 logic controllers.
Each analog input supports selectable 0–10 V, −10 to +10 V,
0–20 mA or 4–20 mA signal ranges, with
12-bit or 11-bit + sign resolution depending on the
configured range. The module uses 24 V DC external power
and 5 V DC internal bus power, and has a
removable screw terminal block. It has four analog
inputs and no analog outputs. Verify your controller,
I/O configuration, power supply and terminal requirements before ordering.
