The TM2DRA16RT expands discrete output capacity within Schneider’s Modicon M2 automation platform. This module measures roughly 3.5 inches long, 2.4 inches wide, and 3.5 inches high. Moreover, it weighs about 0.5 pounds, which suits compact DIN rail cabinets. Engineers add the TM2DRA16RT when controllers need extra relay outputs without major rewiring.
Technical Specifications and Interface Details
The unit provides sixteen relay output channels and therefore switches loads up to 2 A. Specifically, each channel handles resistive and inductive loads at 24 VDC or 240 VAC. Additionally, removable terminal blocks speed up field wiring and module replacement. A ribbon connector links the module directly to the host controller.

Energy Storage and Switching Reliability
Internal capacitors on the TM2DRA16RT provide local energy storage for stable relay drive. Consequently, the module handles inductive loads without excessive contact arcing. This buffering also protects driver circuits during rapid switching cycles. The output stages therefore deliver consistent performance across long service intervals.
Installation and Compatibility Notes
Because the TM2DRA16RT snaps onto standard DIN rail, technicians complete installation in minutes. They should confirm connector orientation before they apply power to the system. Furthermore, the module integrates smoothly with existing Modicon M2 controllers. Always store spare units in anti-static packaging to protect sensitive electronics.
