ماژول رله 5 ولت یک کاناله OMRON SSR

Input section:
the DC +: positive power supply (power supply voltage by relay)
DC-: negative one
CH:  relay module signal triggering end (high trigger enabled)
High and low meaning:
High-level trigger refers to the trigger side (IN) and the negative power supply has a positive voltage between the positive and the power supply is usually connected to the trigger side of a trigger, when the trigger voltage or trigger a positive trigger Voltage, the relay is pull.
Low-level trigger refers to the voltage between the signal trigger terminal and the negative terminal of the power supply is OV, or the voltage of the trigger terminal is lower than the voltage of the positive terminal of the power supply. The negative side of the power supply is connected to the trigger side of a trigger, so that the relay is pull.
Electrical parameters:

Product instructions:
1. Module power supply: the power must be DC, the voltage should be consistent with the relay voltage
When the trigger signal side of the trigger level, the relay will be connected, the device has electricity and work
