TM3AI8 8-Channel Analog Input Module 24V DC Screw Terminal | Schneider Electric

The Original New Schneider Electric TM3AI8 is an 8-channel analog input module for the Modicon TM3 I/O system, designed to expand the analog input capacity of Modicon M221, M241, M251, and M262 logic controllers. It provides 8 configurable 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:
8 analog input channels (voltage/current) | 12-bit resolution (11 bits + sign) | Configurable input ranges: 0-10V, ±10V, 0-20mA, 4-20mA | 1 ms + 1 ms per channel conversion time | Removable screw terminal block (3.81 mm pitch) | 1500V AC isolation between input and supply | IP20 protection | –10°C to +55°C operating temperature | 23.6 mm width
