194L-HE6N-175 | Allen-Bradley Control & Load Switch Actuator – OFF-ON

The 194L-HE6N-175 is a modular light tower from Allen-Bradley’s 194L series. It is used for visual signaling in industrial environments, providing operators with a clear visual indication of a machine’s or process’s status. This particular model features a modular design with multiple segments, such as colored lights, and is often used in manufacturing, assembly lines, and process control environments.

Some key features of the 194L-HE6N-175 include:

• Modular design for easy customization and expansion with additional light segments.
• Multiple light colors (typically red, yellow, green) to indicate different machine states, such as normal operation, warnings, or faults.
• Sturdy construction for industrial environments.
• Easy to install and configure with multiple mounting options.

Yes, the 194L-HE6N-175 can be controlled by a PLC. Typically, a digital output from the PLC can be used to turn on or off the different light segments, such as red, yellow, or green, based on the status of the machine or process. The PLC outputs can be wired directly to the input terminals of the light tower to control the individual segments.

Wiring the 194L-HE6N-175 involves connecting the power supply and input signals for each light segment. Typically:

Power Supply Connection:

• Connect the positive (+) terminal to the 24V DC power source.
• Connect the negative (-) terminal to the common ground.

Signal Inputs for Each Light Segment:

• Each light segment may have a separate input signal (such as a digital on/off signal from a PLC or relay). These inputs control the individual lights (red, yellow, green).
• Connect the signal terminals to your control system (PLC, relay, or other control equipment) to switch the lights on and off based on machine status.

For exact wiring diagrams and connection details, consult the user manual of the product.

Typically, the different light colors in a modular light tower like the 194L-HE6N-175 represent different operational statuses:

• Green: Indicates normal operation or a "go" status.
• Yellow/Amber: Indicates a warning or cautionary state.
• Red: Indicates a fault or an "error" condition that requires attention.

You can configure these colors to correspond to specific system statuses, depending on your application's needs.
