Relay Module (2 Channel) 24V with High/Low Level Trigger Selector

The module has two relays with the coil powered with the voltage of 24 V with optical isolation of the input and mounting holes. The system allows you to control actuators using the microcontroller ports or any development kit using the low or high status – selected by jumper.

Specification

• The VCC supply voltage: 24 V
• Activated by the low or high status – select with jumper H/L
• Relay:
  • Coil voltage: 24 V
  • Maximum load: AC 250V/10A, DC 30V/10A
  • Maximum current: 10A
• Connectors:screw ARK connectors
• Board sizes: 50 x 45 mm
• Diameter of mounting holes: 3 mm

Connection

For proper operation, it is sufficient to connect the power to the relay coil and the digital control signal. The pins are the screw ARK connectors that are connected by any cables with the removed insulation at the ends.

DC+: positive power supply (VCC)

DC-: negative power supply (GND)

IN1, IN2– control inputs of the relays activated by the high or low status

NO: normally open relay interface

COM: Common Interface Relays

NC: normally closed relay interface

Jumper– to change the status of the activation of the relay:

The L position– It is low level trigger when jumper connect to LOW pin

The H position– It is high level trigger when jumper connect to HIGH pin

Examples of application

• Driver of lighting
• The driver of actuators
• Switch for electric devices, including motors
