TM3AI4 4-Channel Analog Input Module 0-10V/4-20mA Screw Terminal | Schneider Electric

The Original New Schneider Electric TM3AI4 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 for voltage (0-10V, ±10V) or current (0-20mA, 4-20mA) 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.

Core Engineering Highlights:
4 configurable analog input channels (voltage/current) | 12-bit resolution (11 bits + sign) | Input ranges: 0-10V, ±10V, 0-20mA, 4-20mA | 1 ms + 1 ms per channel conversion time | ±0.1% absolute accuracy at 25°C | ±0.006% FS/°C temperature drift | 1500V AC isolation (input to supply) | Removable screw terminal block | IP20 protection | 23.6 mm width
