Siemens TXM1.6R-M 6-channel Relay Output Module

Product Dimensions：

The Siemens TXM1.6R-M is a high-performance I/O module from the Desigo TRA (Total Room Automation) and Desigo TX-I/O range. It is specifically designed for switching and signaling in building automation and control systems.

Below is a detailed breakdown of its specifications, benefits, and applications.

## 1. Product Description

The TXM1.6R-M is a plug-in I/O module featuring 6 digital outputs (Relay). It acts as an interface between the automation station (like a PXC controller) and the field devices.

A standout feature of the “-M” variant is the local override facility, which allows technicians to manually control the relays via switches on the front panel, even if the controller is offline.

## 3. Key Product Advantages

• Local Manual Control: The manual switches are invaluable during commissioning or emergency maintenance, allowing hardware testing without software programming.

• Status Transparency: Individual LEDs provide immediate visual feedback on the switching state of each relay.

• Modular Design: Compact footprint that saves space in the control cabinet; it can be swapped out without rewiring the base.

• High Reliability: Built to industrial standards for long-term operation in commercial HVAC environments.

• Seamless Integration: Fully compatible with the Siemens Desigo CC management platform and PXC series controllers.

## 4. Product Applications

The TXM1.6R-M is typically used to control loads that require a simple ON/OFF (binary) command:

• HVAC Systems: Controlling fans, pumps, and small electric heaters.

• Lighting Control: Switching lighting circuits or groups.

• Plant Equipment: Interfacing with chillers, boilers, or motorized dampers.

• Alarms: Actuating acoustic or visual signaling devices.

## 5. Important Considerations & Precautions

• Bus Connection: Ensure the module is properly seated on the TXS1.12F10 power supply or a bus connection module.

• Current Limits: Never exceed the maximum contact rating (5A). For higher loads, use an external contactor.

• Safety Isolation: When switching different voltages on adjacent relays (e.g., 230V next to 24V), ensure compliance with local electrical safety isolation standards.

• Manual Override Risk: Remember that manual override bypasses the automation logic; ensure it is returned to “Auto” after maintenance to avoid energy waste or equipment damage.
