Specification:
Item Type: Relay Module
Material: PCB
Application: Suitable for operation, learning and development of college students, engineers, technicians, factories, individual DIY, electronic enthusiasts, etc.
Relay Parameters: 240V/2A
Input Power: 5VDC
Input Control Signal Voltage:
0-2.5V state low level relay ON
3-5V state high level relay OFF
Quiescent Current: 0mA
Working Current: 12.5mA
Trigger Current: 2mA
DC+: Connect to the positive pole of the power supply (power supply according to the relay voltage)
DC-: Connect to the negative pole of the power supply
CH1: Relay module signal trigger terminal (low level trigger is valid)
Features:
1High level trigger means that there is a positive voltage between the signal trigger terminal (CH) and the negative pole of the power supply. 2Highlevel triggering is a triggering method in which the positive pole of the power supply is connected to the trigger terminal. When the trigger terminal has a positive voltage or reaches the trigger voltage, the relay will pull in. 3Low level trigger refers to when the voltage between the signal trigger terminal and the negative pole of the power supply is 0V, or the voltage at the trigger terminal is lower than the voltage of the positive pole of the power supply, when the voltage is low enough to trigger, the relay pull in. 4Lowlevel trigger is usually a trigger method that connects the negative pole of the power supply to the trigger terminal, so that the relay pull in. 5The input terminal can only be connected to DC power, and the output terminal can only be connected to AC power (the output terminal cannot be connected to DC power). The maximum operating current is 2A.
