== Module Description ==  
The module is designed to control dry contact inputs and to switch low-voltage loads in applications where galvanic isolation is required.

The module contains two N-channel transistors with a common ground.

Each channel has built-in protection against voltage spikes when switching inductive loads (30V TVS).

The load ground (GND) must be connected to the GND terminal of the module (terminal O3 of the extension module).

The load is connected as follows: the '''positive''' terminal of the load is connected to the power supply, and the '''negative''' terminal is connected to the transistor output. To activate the load, a high signal must be applied to the transistor gate.

The illustrations show connection diagrams for an LED and a relay.
