Schneider TM2DRA16RT Digital Output Module

Technical Overview of the Schneider Electric Output Device

The Schneider TM2DRA16RT expands your control system with sixteen digital outputs. This module belongs to the Modicon TM2 range for PLCs. It provides a robust interface for actuators and relays. Each output channel handles up to 2 amps. Consequently, the total current per common return reaches 8 amps.

Key Specifications and Hardware Details

This module weighs approximately 0.2 kg. Its compact dimensions are 90 mm in height, 23.6 mm in width, and 70 mm in depth. The TM2DRA16RT uses a removable screw terminal block for wiring. This design simplifies maintenance and replacement tasks. The device stores no internal energy after power loss. Instead, it relies on external protective circuits.

Installation and Integration Notes

You can mount this digital output module on a DIN rail. It connects directly to a Modicon M221 or M241 controller. Furthermore, the device supports mixed AC/DC loads without additional adapters. Always use an external fast-acting fuse for each group. This practice protects the relay contacts from short circuits.
