General features

Module WL-OC-RGBW1p is a component of the Ampio system. Required voltage to power the module is 11 — 16V DC. The module is controlled via the Ampio LoRa wireless interface.

The module has four OC outputs operating in an RGBW lighting controller mode.

WL-OC-RGBW1p outputs can only be operated in an RGBW lighting controller mode. It is not possible to switch them over to an independent control mode.

RGBW outputs

The module has open-collector outputs allowing for smooth control of LED RGBW lighting supplied with voltage of up to 40V DC. Control is performed by the method of pulse-width modulation (PWM). Internally, each of the outputs allows the connected line to be short-circuited to the module’s ground.

Typical application

  • Smooth regulation of RGBW colour LED lighting.


The dimensions of the module enable its installation in a standard junction box. In order to start it up, it must be connected to the power supply and paired with the module acting as an Ampio LoRa base station in the wired segment of the building automation installation.

The module has two connectors with screw terminals. They enable the connection of power lines of various devices and connection of RGBW LED lighting’s channels of individual colors.

The WL-OC-RGBW1p module allows one to control lighting powered with voltage up to 40V, however, it itself requires voltage in the range of 11 — 16V DC.

If the supply voltage of the controlled light source is not in the range of 11 — 16V DC, it is necessary to provide two power lines - one for the light source and one for the module.

Device status LEDs

On the front of the module there are signalling LED diodes. The green LED with the label STATUS indicates the status of communication on the Ampio LoRa interface.


The module is programmed with a special programmer, available for authorised technicians, and the Ampio Smart Home CAN configurator software. They allow you to modify the parameters of the module and define its behaviour in response to signals directly available to the module. They also provide general information coming from all devices present in the home automation bus.

Before the commencement of configuration activities, it is necessary to pair the device with the module acting as an Ampio Lora base station in the wired segment of the building automation installation. In order to do that, you will need to initiate a search mode for WL-family modules in the base station module in the Smart Home CAN configurator. Then, with the search mode active, press the pairing button on the radio module three times. If pairing is successful, the device that was found will appear on the paired wireless modules list in the Smart Home CAN configurator software.

It is not recommended to use more than 8 Ampio LoRa wireless modules per one base station module. Installing more modules may result in excessive load on the wireless network and improper functioning of the system.

Programming the rules for which the WL-OC-RGBW1p module is to be an executive device, is defined during the configuration of the base station module. In order to create rules whose triggering depends on the state of the WL-OC-RGBW1p module, it is necessary to add it to the device list as a virtual device.
