The Original New Schneider Electric TM3DI32K is a 32-channel discrete input module for the Modicon TM3 I/O system, designed to expand the digital input capacity of Modicon M221, M241, M251, and M262 logic controllers. It provides 32 logic inputs for 24V DC signals (sink/source configurable) with a removable HE10 (MIL 20) connector for high-density wiring. Part of the Modicon TM3 expansion family, it features a simple interlocking assembly mechanism for quick DIN rail mounting.
