Schneider Electric TM3TI4 Modicon TM3 Analog Input Module 4xTemperature

Schneider Electric Modicon TM3 analog input module with 4 configurable channels. Each channel supports thermocouple (J, K, T, E, N, R, S, B, C, L), RTD (Pt100, Pt1000, Ni100, Ni1000), voltage (±10V, 0-10V), and current (0-20mA, 4-20mA) signals. 16‑bit resolution, 500V AC isolation between channels and bus. Screw terminal block. Part of Modicon TM3 I/O system for M221, M241, M251, and M262 PLCs. Compact 23.6 mm width for space‑efficient panel integration.

Applications:

• Temperature monitoring with thermocouples or RTD sensors in industrial processes

• Precision measurement for HVAC and building automation

• Temperature monitoring in packaging machinery
