The module has two relays with the coil powered with the voltage of 12 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: 12 V
- Activated by the low or high status – select with jumper H/L
- Relay:
- Coil voltage: 12 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.
Module Interface:
DC+: positive power supply (VCC)
DC-: negative power supply (GND)
IN1, IN2– control inputs of the relays activated by the high or low status
Relay Outputs:
NO: normally open relay interface
COM: Common Interface Relays
NC: normally closed relay interface
High and low level trigger options:
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
