Product Overview
The Schneider TM3DI8 is an 8-channel discrete input expansion module from the Modicon TM3 series, designed to extend the digital input capacity of Modicon M221, M241, M251, and M262 controllers. It supports 24 VDC inputs with sink or source logic, conforming to IEC 61131‑2 Type 1 standards.
Its compact design and DIN-rail mounting make it ideal for machine-level automation. Moreover, per-channel LED indicators provide immediate input status feedback, simplifying commissioning and troubleshooting. Therefore, it is a reliable and cost-effective solution for industries such as packaging, material handling, and general automation applications.
