PATLITE is proud to announce the launch of its new LR5-LAN Series Signal Tower, designed to simplify operations and improve network integration. The LR5-LAN Series features a robust 50mm diameter, IP54 or IP65-rated, 24V DC unit with a sleek off-white body, offering up to five LED tiers and buzzer modules.
The LR5-LAN Series integrates seamlessly with network devices, including PCs, servers, and network cameras, enabling easy remote monitoring and management via a standard web browser. With the capability to control the signal tower through universal protocols like HTTP(S), Modbus/TCP, and SOCKET, users can effortlessly send commands from any compatible device.
With 7 preset LED control patterns, the LR5-LAN Series simplifies setup and operation, offering an ideal solution for industrial environments where clear, reliable signaling is essential.
Features
LR5-LAN Series Signal Tower Features:
Direct LAN Control from Industrial PCs/PLCs Makes Configurating & Signaling Easy
- Before: In an industrial PC-controlled system, a contact output board was being used, leading to an increase in component count and complications in inventory and delivery management.
- After: With direct control of signal towers via HTTP or Modbus/TCP, the need for a contact output board has been eliminated.

Usage Scenarios
- Control with Industrial PC/PLC - Command control directly from Industrial PCs or PLCs.
Eliminate the need for contact output boards and reduce the number of required contact points.

- Notification from Higher-Level Systems - SCADA and production management systems can display status and alerts using standard protocols. By visualizing alerts not only on monitors, but also through signal towers (which are common in manufacturing environments), the operators can quickly grasp information and prevent oversights.

Simple Software Design
- Command Generation Feature - After logging into the LR5-LAN via a web browser, select the desired operation from the setting screen to display the corresponding command. This allows for easy command verification without the need to read the user manual, reducing time spent on software development.
- Sample Source Code - Sample source code for operating the LR5-LAN is available on the product’s web page. Various programming languages are provided for Windows® and Linux, allowing you to quickly test it using your preferred or project-specific language.
- Comprehensive Flashing Presets - Seven preset patterns for LED control are available. Since Flashing operations can be executed through command control alone, it reduces the effort required for setting clock pulses in PLCs.

Host Device Connection Verification Function
The connection with the device can be checked. If the connection is lost, the LED unit provides a notification, enabling host-to-host Ping monitoring.

Reduce Wiring Labor
Reduce Man-hours
Power is supplied with 24V DC, and the unit is controlled via an RJ-45 connector with LAN cable. The wiring work can be reduced in comparison to wire leads.
Easy Setup
By using the optional ADP-001C, power can be supplied from an AC outlet. Even if 24V DC is not available, the ADP-001C can easily be implemented without construction.
