Product Features
Direct LAN Control from Industrial PCs/PLCs Makes Configuration & Signalling 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(S) 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 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 Preset Patterns
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.
