Schneider Electric TSXDMF344A IO Extension Module

The Schneider Electric TSXDMF344A is a 34-point digital input/output relay extension module for Modicon TSX 17 PLC systems, designed to expand discrete I/O capacity in factory automation. It provides 22 digital inputs (110 VAC isolated) and 12 normally open relay outputs, all powered from 110–240 VAC at 50/60 Hz, and it mounts as a PLC extension block. This module supports digital I/O expansion for sensors, contactors, indicator lights, and solenoid valves in conveyors, packaging machinery, material handling equipment, and assembly lines. As part of the Modicon TSX 17 family from Telemecanique (Schneider Electric), the TSXDMF344A carries the MPN TSXDMF344A and is commonly used as an OEM direct replacement for expanding control system I/O. Common replacements include Schneider Electric TSXDMF344A and Telemecanique TSX DMF 344A.
