Product Introduction
When upgrading your automation system, the Schneider TM3TI4 analog input module provides a seamless transition to modern Modicon TM3 architecture. This module is part of the Modicon TM3 family and offers 4 analog/temperature inputs with screw terminal connections, operating at 24 VDC. It is designed to replace older analog modules while integrating with M221, M241, M251, and M262 controllers.
Technical Specifications
The TM3TI4 supports a wide range of input types:
- Current: 4...20 mA, 0...20 mA
- Voltage: 0...10 V, -10...10 V
- Thermocouples: Types J, K, R, S, B, T, N, E, C with specific temperature ranges
- Temperature probes: Ni100, Ni1000, Pt100, Pt1000

Compatibility & Integration
The Schneider TM3TI4 is fully compatible with Modicon M221, M241, M251, and M262 controllers. It connects via the TM3 bus and is mountable on standard DIN rails. This makes it an ideal upgrade for systems using older analog modules, providing enhanced functionality without complex rewiring.
Industry Applications
In process control and manufacturing, the TM3TI4's ability to handle multiple sensor types reduces inventory and simplifies setup. Use it for temperature monitoring in HVAC, for current loop sensors in conveyor systems, or for voltage signals in motor drives. The high accuracy ensures reliable data for critical processes.
Installation & Setup Guidance
Mount the module on a TH35-15 or TH35-7.5 rail. Use twisted shielded pair cables for connections under 30 m. The removable screw terminal block accepts up to 1.5 mm² wire. Ensure the 24 VDC supply is within limits before powering. The green LED indicates power status.
