TXM1.16D SIEMENS

TXM1.16D SIEMENS Basis unit

Product  Description：

The Siemens TXM1.16D is a Digital Input Module belonging to the TX-I/O™ product range within the Siemens Desigo Building Automation System. It is designed to extend the input capabilities of compatible Siemens automation stations, facilitating the monitoring of various field devices.

Product Specifications

• Module Type: Digital Input Module

• Product Range: TX-I/O™

• Number of Inputs: 16 Digital Inputs (DI)

• Input Configuration: All 16 digital inputs are individually configurable as:

  • Message signal (status signals from maintained contacts)

  • Message impulse with storage functions (status pulses)

  • Counter impulse (up to 8 of the 16 inputs can be used for counting pulses up to a maximum of $10 \text{ Hz}$)

• Status Indication: Each of the 16 digital inputs is signaled with a dedicated green LED for easy status indication and fast diagnostics.

• Operating Voltage (Supply): $\text{DC } 22.5 \ldots 26 \text{ V}$

• Power Consumption: $1.4 \text{ W}$

• Contact Sensing Voltage: $\text{DC } 21.5 \ldots 25 \text{ V}$

• Contact Sensing Current: $1.6 \text{ mA}$ (initial current $10 \text{ mA}$)

• Physical Design: Compact DIN format housing, featuring a separate terminal base and a plug-in I/O module.

• Dimensions (W x H x D): $64 \text{ mm} \times 77.5 \text{ mm} \times 98 \text{ mm}$ (approximately)

• Net Weight: $0.199 \text{ kg}$

Product Advantages

• High Density and Versatility: Provides 16 digital inputs in a compact DIN format, maximizing I/O capacity within the control panel. The ability to individually configure the inputs for status, pulse, or counting signals offers high flexibility.

• Modular and Hot-Swappable Design: The module consists of a terminal base and a plug-in electronics module. This design allows the electronics module to be replaced quickly (hot-swappable) without rewiring the field devices or interrupting the operation of other modules on the bus, significantly reducing maintenance time.

• Easy Installation and Commissioning: Features a self-establishing bus connection and terminal isolation function, simplifying both mounting and field commissioning.

• Clear Diagnostics: Each input point is equipped with a green LED, providing immediate visual feedback on the operational status of the connected device.

• Direct Field Device Connection: All connection terminals are located directly on the I/O unit, eliminating the need for separate terminal strips and simplifying wiring in the panel.

• System Integration: Perfectly compatible with Siemens Desigo automation stations, such as the PXC series (e.g., PXC5.E24, PXC7.E400L), ensuring seamless integration into a complete Building Automation System (BAS).

Important Considerations (Precautions)

• Supply Voltage: Ensure the supplied operating voltage is within the specified range of $\text{DC } 22.5 \ldots 26 \text{ V}$.

• Cable Length and Shielding: The permitted cable length for inputs is generally maximum $300 \text{ m}$. Proper cable shielding and grounding should be used, especially for counter impulse signals, to prevent interference and maintain signal integrity.

• Contact Type: The module monitors status signals from volt-free/dry contacts (no potential). Mechanical contacts must be volt-free, and electronic switches must comply with SELV (Safety Extra-Low Voltage) or PELV standards.

• Ventilation and Environment: The module is designed for installation inside an enclosure. Ensure adequate ventilation is provided to keep the operating ambient temperature below the maximum limit of $50^{\circ}\text{C}$ to maintain reliability.

• Counter Function Limitation: Note that the high-speed counter function ($\text{up to } 10 \text{ Hz}$) is typically limited to only 8 of the 16 available input points.
