The RL5-ND sensor uses a Japanese chip with a measurement range of 1 to 65,535 lux. The measurement accuracy is 1 lux, with a measurement error of 5%.
The lux meter sensor measures ambient light intensity in industrial and non-industrial environments such as greenhouses, poultry farms, livestock centers, server rooms, laboratories, cold storage facilities, office buildings, residential buildings, and more.

Support for Modbus RTU protocol over RS-485

Support for Modbus TCP protocol over LAN

Provides values of 3 physical sensors simultaneously along with the average of all three.

Lux measurement range: 1–65,535 lux

Measurement accuracy: 1 lux

Waterproof Package with IP64 Standard

Ability to automatically send logs to the server

Equipped with a professional web service for configuration via browser
The relays in the RL5-ND sensor have two different control modes:
Mode 1: Controlled via Modbus network
Mode 2: Based on ambient lux level
Each relay can be configured with its own mode independently. For example, one relay can be set to operate based on lux level, while the other can be configured to operate via the Modbus network.
When the relays are set to control based on ambient light intensity, they operate within a defined range: one lux value is set as the maximum light intensity (for example, 25 lux), and another as the minimum light intensity (for example, 18 lux). According to these values, the control range becomes 18 lux to 25 lux.
On this display, the light intensity measured by the sensor is shown by default. At any time, you can press the menu button to enter the menu.
The device is equipped with a 1.3-inch OLED display. It has four keys that are used for configuring the device settings.
If you want to use this sensor over the network (you assign an IP address to the device), entering the IP will open the web service, where all configurations can be done through the web interface.
One of the key applications of the web service is that, for example, if these sensors are deployed in an internal Ethernet network of an organization or refinery, all configurations can be set remotely through the network.
If the environment where you are using this sensor has a modem with a valid IP, by applying certain network settings you will be able to remotely connect to the device’s web service via the Internet, view the lux values, and apply any configurations directly to the device.

Yes. Since the device enclosure has an IP66 protection rating against water and dust ingress, this product can be used in outdoor environments. However, it is not recommended to expose it continuously to rain or direct water spray.
Due to the protective cover on the sensor, sudden sprays of non-acidic liquids are repelled and do not cause any damage to the sensor.
Since this sensor communicates via the Modbus protocol with devices such as PLCs, RTUs, and HMIs, you can view the measurements on industrial HMI displays and your personal computer monitor.
Yes. One meter of flexible four-core cable (power + RS-485) with a thickness of 0.25 mm² is included with the product.
Via the Modbus-RTU network
Yes, the sensor’s slave address can be changed via software using Modbus commands.
The components used in this sensor are manufactured in the USA and Switzerland.
Yes, according to Modbus protocol standards, this is possible. For more information and details on how to differentiate sensor data, you can refer to the sensor setup tutorial file.
You can find all tutorials and necessary files on the product page under the “Product Videos” and “Downloadable Files” tabs. Click here.
Some PLCs have an RS-485 port, allowing the sensor to connect directly. However, for PLCs without an RS-485 port, the sensors must be connected via RS-485 expansion cards.
Due to the sensor’s casing material, it cannot be installed directly inside a furnace. However, the company can provide the sensor with a half-meter cable, allowing customers to place the sensor circuitry outside while installing the sensor itself inside the furnace.
