Product Description (Detailed Explanation)

The TXM1.6R-M features 6 independent relay outputs (volt-free contacts). It is part of the modular TX-I/O system, where modules are snapped onto a bus connection terminal base.

The “-M” designation signifies that this module includes Manual Overrides. On the front panel, each of the 6 channels has an individual slide switch that allows technicians to manually force the relay into the ON or OFF position, or return it to AUTO (system control). This is indispensable for commissioning, testing, and emergency manual operation of fans, pumps, or dampers.

Product Parameters (Technical Specifications)

Product Advantages (Key Benefits)

• Integrated Manual Override: Allows direct field control without the need for a laptop or software access, significantly speeding up the troubleshooting process.

• Status Feedback: The position of the manual switch is transmitted back to the automation station, so the building operator is alerted if a device is left in manual “Hand” mode.

• High Versatility: Capable of switching both high voltage (250 VAC) and low voltage (24 VDC), making it suitable for a wide variety of electrical loads.

• Modular Hot-Swapping: The electronic module can be replaced while the system is powered and without removing field wires from the terminal base.

• Self-Check Logic: Includes internal self-monitoring to ensure data integrity between the controller and the physical relay state.

Precautions (Important Notes)

• Terminal Base Required: This module must be plugged into a TXS1.BP or TXS1.BS terminal base to connect to the I/O bus.

• Total Current Limit: Ensure the total current across all 6 relays does not exceed the maximum thermal rating of the module’s bus connection.

• Safety Isolation: When switching 250 VAC, ensure that the safety distance and insulation rules for high-voltage wiring are followed as per local regulations.

• Manual Mode Risks: Be aware that forcing a relay to “Hand” mode bypasses all software interlocks and safety logic (e.g., frost protection). Use with caution.

Product Applications (Typical Use Cases)

• Fan Control: Switching supply and extract fans in Air Handling Units (AHUs).

• Pump Sequencing: Managing the operation of circulating pumps in heating and cooling circuits.

• Boiler & Chiller Enable: Providing dry-contact enable/disable signals to large-scale plant equipment.

• Lighting Zones: Controlling high-voltage lighting circuits in commercial buildings or parking garages.

• Motor Interlocks: Interfacing with motor starters or Variable Frequency Drives (VFDs) for start/stop commands.
