Specification:
Item Type: 12V Relay Module
Quiescent Current: 2mA (with power indicator light), 0.5mA (without indicator light)
Working Current: 45mA at 12V
Anti Interference: The interference time of the input switch is 20ms, that is, when the switch is less than 20ms, it is considered as an interference signal and will be ignored.
Output Mode: Relay contact, no electricity (dry contact)
COM: Public
NO: Normally open, that is, the module is disconnected from COM when it is not connected to power (or closed).
NC: Normally closed, that is, the module is connected to COM when it is not connected to power (or closed).
Module Size: Approx. 58 x 32mm / 2.3 x 1.3in, Height: Approx. 18mm / 0.7in
Mounting Hole: Approx. 54 x 28mm / 2.1 x 1.1in, Aperture: Approx. 2.6mm / 0.1in
Terminal Description:
V+COM: The positive input of the module power supply, which is also the common line of the 2 switches.
V-: The negative input of the module power supply.
ON: Power on button, press the relay will immediately pull in, and keep pulling in (until the OFF button is pressed).
OFF: Shut down button, press the relay to disconnect immediately
Features:
1[2 BOTTON CONTROL] 2 button switch relay module, suitable for various situations where 2 buttons are used to control on and off respectively. 2[FOR MOTOR] Cooperate with the travel switch to realize the CW and CCW of the motor, so that the travel is within a fixed range. 3[TRIGGER ALARM] Combine the power button with the vibration sensor to trigger the alarm, that is, automatically trigger the alarm and stop manually. 4[GOOD PROTECTION] The relay module has power supply reverse connection protection, and the module will not be damaged when the power supply is reversed. 5[WITH INDICATORS] The red light is on, it means the power of the module is on, and the green light is on, it means the relay is processing the pull in state. 6[HIGH LEVEL] High level trigger input mode, can be used to extend the weak current signal to control the strong current equipment.
Package List:
1 x Relay Module
