The switch module has multiple uses. It allows the software to switch on and off a 5 VDC signal. Generally they are used to switch on and off a solid state relay. Solid State Relays are used to switch higher amperage loads. The switch modules 5 volt DC output is suitable to control solid state relays that operate on a 3-24VDC signal.
Voltage : 5VDC
Max Current: 100mA
