Product Overview
The Schneider Electric TM3AI8 is a
Modicon TM3 eight-channel analog input expansion module
designed for supported M221, M241, M251 and M262 logic controllers.
Its eight input channels can be configured for 0–10 V DC,
−10 to +10 V DC, 0–20 mA or 4–20 mA signals, using
12-bit or 11-bit + sign resolution according to the
selected range. The module requires 24 V DC external power
and uses the TM3 internal bus for communication and logic power.
Removable screw terminals support signal and supply wiring.
This input-only module has no analog outputs.
Confirm the controller, configured signal ranges, supply wiring and
exact screw-terminal model before ordering.
