- Description
The Schneider Electric TM3TI4 is a Modicon TM3 expansion module that adds 4 analog inputs configurable for current, voltage, thermocouple or RTD temperature sensing, at 16-bit (or 15-bit plus sign) resolution, to Modicon M221, M241, M251 and M262 logic controllers running on a 24 V DC supply. Input impedance is 50 ohms on current ranges and 1 megohm on voltage ranges, with 0.2% full-scale accuracy at 25 degrees C.

Selection Notes
Pick the TM3TI4 when the application needs only 4 channels, or a mix of current, voltage and thermocouple/RTD signal types on a single module. The TM3TI8T in the same range offers 8 dedicated temperature channels instead, so choose it when more temperature inputs are needed and current/voltage inputs are not.
