The module contains two N-channel transistors with common ground. | |||
Each channel has built-in protection against voltage surges when switching inductive load (TVS for 30V). | |||
The ground (GND) of the load must be connected to the GND terminal of the module (O3 terminal of the extension module). | |||

Configuration of the web interface is carried out in the section Configs => Hardware Modules Configuration. | |||
Select "WBE-DO-OC-2: Dual Open-Collector Output Module" in the Internal slot 1 or 2 section (depending on the slot number) and click Save. | |||
Once added, two additional outputs appear in the Devices next to the controller outputs (the Discrete I/O section). | |||
When adding a device is detected immediately, a reboot is not required. | |||

The load is connected as follows: "plus" load is connected to the power supply, "minus" is connected to the transistor output. For the load to start working, you need to apply a high level to the gate of the transistor. | |||
The illustrations show the wiring diagrams of the LED and relay. | |||

The relay control signals are on the SDA (K1) and SCL (K2) contact of the extension module. | |||
