Schneider TM2DRA16RT Product Review: Key Features and Applications
The Schneider TM2DRA16RT discrete output module expands the Modicon M238 logic controller with 16 relay outputs. Each output uses a normally open contact and handles up to 2 A at 240 V AC or 30 V DC. Engineers gain a robust solution for controlling actuators, solenoids, and indicators in industrial automation systems.
Output Specifications and Performance
Each channel delivers 2 A, with a common point current limit of 8 A. Two common points allow flexible load grouping. Contact resistance stays below 45 mΩ, reducing energy loss. The module responds within ≤10 ms from off to on and ≤5 ms from on to off. It can switch minimum currents as low as 0.1 mA at 0.1 V DC, suiting low-power signals.
Isolation and Durability
Channels withstand 1500 V isolation between each other and between groups. The logic interface withstands 2300 V isolation. Mechanical durability reaches 20 million cycles. Electrical durability spans 100,000 cycles for resistive loads at 2 A AC/DC and for inductive loads under specified conditions. These ratings ensure long service life under typical industrial conditions.
Power Consumption and Physical Design
With all outputs active, the module draws 30 mA from 5 V DC and 40 mA from 24 V DC. A local display block shows status. Connection uses a removable screw terminal block for easy wiring. The module mounts on a 35 mm DIN rail and weighs 0.145 kg. Dimensions are 90 mm height, 84.6 mm depth, and 27.3 mm width, making it compact for control cabinets.
Compatibility and Environmental Compliance
The TM2DRA16RT works with Modicon M238, Advantys OTB, and Twido platforms. This versatility simplifies system integration. As a Green Premium product, it meets RoHS and REACh requirements. It includes an environmental profile and end-of-life instructions, supporting sustainability goals.
Practical Applications
Use this module to control relays, contactors, solenoid valves, and lamp banks. The 16 outputs provide ample points for discrete control in manufacturing, packaging, and material handling. Its high current capacity and fast switching make it a reliable choice for demanding environments.
In summary, the Schneider TM2DRA16RT offers a balanced combination of output density, current capacity, and durability. It stands as a practical relay output expansion module for Modicon M238-based automation systems.
