Product Description

The TXM1.6R-M is a modular I/O unit providing six independent relay outputs. Each channel is designed to switch AC or DC loads for HVAC and building automation systems. A key feature of this model is the front-panel LCD display and manual switches, which allow technicians to override the automation station’s commands during commissioning, testing, or emergency maintenance.

Product Parameters

Key Product Advantages

• Manual Control: The built-in LCD and buttons allow for “Hand-Off-Auto” (HOA) functionality directly on the module, which is invaluable for troubleshooting without a laptop.

• Visual Status: The LCD provides clear feedback on the current relay position and indicates whether the output is in Manual or Automatic mode.

• Versatility: Capable of switching a wide range of voltages, from low-voltage signals to 250V mains power for fans or pumps.

• Plug-and-Play: Uses the TX-I/O island bus for automatic addressing and power, significantly reducing wiring time.

• Safety & Maintenance: The module can be replaced while the terminal base remains wired, and the system automatically re-configures the new module upon insertion.

Important Considerations (Precautions)

• External Fusing: Relay outputs are not internally protected against short circuits. External circuit breakers or fuses must be installed according to local regulations.

• Mixed Voltages: If different voltages are used on the same module (e.g., 24V and 230V), specific safety distances and wiring rules must be followed to maintain insulation.

• Inrush Currents: Be cautious when switching capacitive loads (like LED drivers) or large inductive loads; ensure the peak inrush current does not exceed the relay’s rated limits.

• Manual Mode Risk: When in manual mode, the automation station (PXC) loses control. Ensure all manual overrides are returned to “Auto” after service to prevent system malfunction.

Applications

• Plant Control: Controlling 1-speed or 2-speed fans, pumps, and electric heaters.

• Lighting Control: Switching lighting circuits based on schedules or occupancy.

• Interlocking: Providing volt-free signals to third-party equipment like Chillers or Boilers.

• Staging: Sequential control of multi-stage cooling or heating equipment.
