TXM1.16D Siemens input module

Description

TXM1.16D Siemens input module

Product Dimensions：

The Siemens TXM1.16D is a digital input module belonging to the TX-I/O™ series, designed for use in modern building automation systems (such as Siemens’ Desigo system) and industrial automation applications, often compatible with Siemens Programmable Logic Controllers (PLCs).

• Function: It is used to monitor and detect the on/off status (digital signals) of various external field devices, such as switches, window contacts, occupancy sensors, and other volt-free contacts.

• Capacity: It provides 16 digital input channels.

• Indication: Each of the 16 inputs is signaled by a green LED to indicate its operational status.

• Configuration: The 16 digital inputs are individually configurable to support different functions:

  • Message signal (maintained contact).

  • Message impulse with storage functions (status pulses).

  • 8 inputs can be configured as counter impulses for frequencies up to a maximum of 10 Hz.

⚙️ Product Specifications (Technical Parameters)

⭐ Product Advantages

• High Density: Offers 16 digital inputs in a compact, space-saving design, ideal for control cabinets with limited space.

• Versatile Configuration: Inputs are individually configurable, supporting status signals, pulse detection (with memory), and counter pulses, offering flexibility for various monitoring needs.

• Modular Design: Features a separate terminal base and a plug-in I/O module.

  • This allows for quick module replacement (in seconds) without rewiring or affecting other modules.

  • The self-establishing bus connection ensures maximum ease of installation.

  • The terminal isolation function allows for fast commissioning.

• Integration: Seamless integration and compatibility with Siemens’ Desigo building automation system and other Siemens PLCs.

• Reliability: Robust and engineered for consistent performance in critical commercial and industrial environments.

• Direct Connection: Terminals are directly on the I/O module, facilitating the direct connection of field devices.

⚠️ Important Precautions

1. Power Supply: Ensure the module is supplied with the correct operating voltage, DC $22.5…26\text{ V}$. Incorrect voltage can damage the module.

2. Safety Standards: The connected field devices must comply with the requirements for Safety Extra-Low Voltage (SELV) or Protection by Extra-Low Voltage (PELV) standards.

3. Digital Input Type: Mechanical contacts connected to the digital inputs must be volt-free. Electronic switches must comply with SELV/PELV standards.

4. Cable Length: The permitted cable length for digital inputs is a maximum of $300\text{ m}$.

5. Installation: The modular components (terminal base and I/O module) should be handled carefully during installation and replacement to maintain the integrity of the bus connection. Always refer to the official datasheet (CM2N8170) and installation instructions before setup.

🌍 Product Applications

The TXM1.16D module is a versatile component primarily used in building automation and industrial control for status monitoring. Typical applications include:

• Building Management Systems (BMS):

  • Monitoring the open/closed status of window/door contacts.

  • Monitoring the status of switches (e.g., manual overrides).

  • Integrating occupancy sensors for lighting or HVAC control.

• HVAC Monitoring: Monitoring the on/off status of fans, pumps, or filters.

• Security System Integration: Receiving status signals from security sensors or alarm points.

• Lighting Control: Monitoring light switch status for centralized control.

• Machine Control/Process Monitoring: Collecting binary data (e.g., limit switch status) from industrial machinery in automation setups.

• Data Acquisition: Counting pulses from meters or other devices up to $10\text{ Hz}$.
