Schneider Electric TM3DM24R – 24-Point I/O Expansion Module for Industrial Automation

The Schneider Electric TM3DM24R is a modular 24-point I/O expansion unit designed for use with Modicon M2xx series PLC systems. It offers 16 digital inputs and 8 relay outputs, allowing increased I/O capacity and flexible configuration for a variety of industrial automation tasks. The module supports easy installation and integration, making it ideal for system expansions, upgrades, and custom control solutions.

Key features and benefits:
• 24 I/O points (16 digital inputs + 8 relay outputs) — expands PLC I/O capacity.
• Compatible with Modicon M221, M241, M251, M262 controllers — seamless integration with Modicon M2xx series.
• Modular design — plug-and-play installation, simple wiring (screw terminals).
• Flexible configuration — suitable for various input/output needs (sensors, actuators, relays).
• Enables scalable automation systems — adds I/O without replacing PLC core.

Typical applications:
• Machine control panels and small-to-medium industrial automation systems.
• Conveyor and material handling systems requiring multiple I/O points.
• Sensor and relay-based control systems — e.g. start/stop logic, safety interlocks, status monitoring.
• Retrofit or expansion of existing Modicon M2xx PLC systems.
• Production line automation, building automation, environmental control systems.
