The Original New Schneider Electric TM3DI16 is a 16-channel discrete input module for the Modicon TM3 I/O system, designed to expand the digital input capacity of Modicon M221, M24 1, M251, and M262 logic controllers. It provides 16 logic inputs for 24V DC signals (sink/source configurable) with a removable screw terminal block for secure field wiring. Engineered for reliable industrial signal acquisition, the module is the screw terminal version of the TM3DI16 series — the spring terminal variant is available as TM3DI16G. Part of the Modicon TM3 expansion family, it features a simple interlocking assembly mechanism for quick DIN rail mounting.
