Schneider TM2DDO8TT Discrete Output Module

Product Overview: The Schneider TM2DDO8TT is a dedicated discrete output expansion module designed to extend the digital output capabilities of Modicon M238 logic controllers. This module provides 8 high-speed transistor outputs, operating at 24V DC with source logic, making it ideal for rapidly switching loads in demanding industrial automation applications. Featuring a convenient removable screw terminal block, built-in short-circuit and overload protection, and an exceptionally fast response time, the TM2DDO8TT offers a reliable, robust, and efficient solution for controlling various actuators and indicators. It is also compatible with Twido and Advantys OTB ranges.

Key Features:

• 8 Transistor Outputs: Provides eight independent, high-speed transistor output channels for precise control.
• 24VDC Source Logic: Operates with 24V DC and configured for source logic, compatible with common industrial loads.
• Removable Screw Terminal: Ensures flexible, secure, and user-friendly wiring connections, simplifying installation and maintenance.
• Rapid Response Time: Delivers ultra-fast switching with a response time of 450 µs for both turn-on and turn-off, crucial for time-sensitive applications.
• Integrated Protections: Equipped with automatic reactivation for short-circuit and overload protection, enhancing system reliability and longevity.
• High Current Capacity: Offers a discrete output current of 0.5 A per channel (0.6 A continuous per channel) and a maximum of 4 A per output common.
• Robust Isolation: Provides 500 V isolation between channels and internal logic for enhanced electrical safety and signal protection.
• Compact & DIN Rail Mountable: Space-saving design optimized for efficient panel integration on a standard 35 mm symmetrical DIN rail.
• Broad Compatibility: Primarily designed for Modicon M238 logic controllers, also compatible with Twido and Advantys OTB series.
