Supplied from remaining channel stock; full specifications, lifecycle and same-series options are below.","salesMarkdown":"## Overview The TM2DDO8TT is a Schneider Modicon M238 logic controller discrete output module, order code TM2DDO8TT, providing 8 source transistor outputs rated at 0.5 A per channel at 24 V DC. This module delivers eight sourcing (positive-logic) transistor outputs, each capable of switching up to 0.5 A at 24 V DC. The transistor output type means fast, solid-state switching with no mechanical wear — suited for high-cycle solenoid valves, indicator lamps, and DC motor contactors where relay bounce would be a concern. Both short-circuit and overload protection are built in with automatic reactivation, so a temporary fault on one output does not lock the module out. The response time of 450 ms is typical for a transistor output stage driving inductive loads; the maximum inductive load rating of 10 mH and tungsten load of 12 W define the acceptable load profile per channel. A single common point groups all eight outputs, meaning the module sinks current through one shared return. The switching current of 0.6 A per channel is the peak repetitive rating; continuous operation at 0.5 A per channel is the design limit. ## Applications As a Modicon M238 expansion module, the TM2DDO8TT fits into compact machine control systems — packaging lines, material handling stations, small conveyor cells, and OEM equipment where the M238 CPU handles logic and this module adds discrete DC output capacity.","metaTitle":"Schneider TM2DDO8TT Modicon M238 8-Out Transistor Module","metaDescription":"Schneider TM2DDO8TT discrete output module: 8 source transistor outputs, 0.5 A, 24 V DC, DIN-rail, discontinued.
