The Original New Schneider Electric TM3TI4 is a 4-channel analog input module for the Modicon TM3 I/O system, designed to expand the analog measurement capability of Modicon M221, M241, M251, and M262 logic controllers. It provides 4 configurable input channels supporting voltage (±10V, 0-10V), current (0-20mA, 4-20mA), thermocouple (types K, J, R, S, B, E, T, N, C), and 3-wire RTD (Pt100, Pt1000, Ni100, Ni1000) signals. A removable screw terminal block ensures secure field wiring. Part of the Modicon TM3 expansion family, it features a simple interlocking assembly mechanism for quick DIN rail mounting.
