Module Interface:

Input Part:

DC+: Connect the power supply positive (press the relay voltage power supply)

DC-: The cathode of a power supply

CH: Relay module signal trigger end (high level trigger effective)

High level triggering refers to the fact that there is a positive voltage between the signal High level trigger refers to the signal trigger end (IN) had a positive voltage andthe negative pole of the power supply is usually between, and the triggering end of a trigger connected with the positive pole of a power supply, when the triggerend has a positive voltage or reached the trigger voltage, the relay is attracted.

Low level trigger refers to the signal triggering voltage between the end and the negative electrode of the power supply is OV, or trigger terminal voltage lower voltage than the positive power supply voltage, low to can trigger, so that relay,is usually the cathode of the power supply and the triggering end of a trigger mode connection, so that the relay is attracted.

1 x 8 Channel Solid State Relay Module

1. The power supply of the module: The power supply must be DC, and the voltage must match the voltage of the relay

2. Wiring method: When the signal trigger terminal has a low level trigger, the relay will be turned on, and the device will work with electricity
