Product Description

The TXM1.8D provides 8 digital inputs in a compact, DIN-rail mounted housing. A standout feature is the integrated three-color LED (green, yellow, red) for each input, which provides immediate local visual feedback on the status of connected devices. It is part of the modular “island bus” system, which allows it to receive power and communication signals directly from the bus with minimal wiring.

Product Parameters

Key Product Advantages

• Highly Configurable: Each input can be individually software-configured as a status signal, a status pulse (with memory function), or a counter pulse.

• Visual Diagnostics: The three-color LEDs are programmable via the automation station to show specific states (e.g., Green for “OK,” Red for “Alarm,” Yellow for “Maintenance”).

• Simple Installation: The TX-I/O island bus design eliminates the need for complex internal wiring between modules; they simply snap together.

• High Reliability: Built for industrial building environments, supporting a maximum cable length of 300 meters for inputs.

• Space Saving: Offers a high density of 8 points in a slim 64mm width.

Important Considerations (Precautions)

• Volt-Free Contacts: Inputs are not electrically isolated from the system electronics. Mechanical contacts must be volt-free (dry contacts).

• Electronic Switches: If using electronic switches, they must comply with SELV/PELV standards.

• Terminal Base: The module requires a compatible terminal base for wiring (it is a two-part design: terminal base + plug-in I/O module).

• Bus Limits: Ensure the total power consumption of all modules on the TX-I/O bus does not exceed the capacity of the power supply module (e.g., TXS1.12F4).

Applications

• HVAC Monitoring: Tracking the status of fans, pumps, and dampers (Run/Stop feedback).

• Safety & Security: Monitoring fire alarm contacts or door position switches.

• Energy Management: Acting as a pulse counter for water, gas, or electricity meters (up to 10 Hz).

• Fault Reporting: Collecting alarm signals from boilers, chillers, or elevators for centralized monitoring in a Building Management System (BMS).
