Siemens I/O Module TXM1.8X-ML Digital, Analogue 24V dc

This I/O module provides mixed digital and analogue input/output capability for automation and building-control environments. It is designed to Interface control systems with field devices, offering an 8-point I/O configuration and operation from a 24V supply. The unit is suitable for installations requiring compliance with recognised electrical and safety standards and for use in industrial automation or building-control systems.

• Eight I/O points enabling Compact multi-signal handling
• Accepts digital and analogue signals for versatile interfacing
• Operates from a 24V supply for common control-voltage systems
• Narrow profile minimises panel space usage

• Suitable for building-services control panels requiring mixed I/O
• Ideal for interfacing sensors and actuators in factory automation
• Used with central controllers in HVAC and access systems
• Can be used for monitoring and control in electrical distribution

The device is specified to function at ambient temperatures up to 50°C, so ventilation or location selection should prevent exposure above this threshold.

Allowance should be MADE for the unit’s external footprint of 77.5 x 64 x 98mm when positioning on DIN rails or within enclosures.

The unit accepts both digital and analogue I/O, enabling handling of multiple sensor and actuator signal types across eight points.
