Description

The VT12 Relay Module is a compact dual-channel power and switching unit designed for controlling any 12V DC devices up to 1A per output. With integrated relays and dry contact inputs, the module offers reliable switching and power delivery in a wide range of automation and control applications.

  • Dual Independent Outputs (A and B): Each output provides:

    • 12V DC Power

    • Relay-Switched Line

    • Ground (GND)

  • Dry Contact Inputs (A and B): Trigger relays using external dry contacts such as switches, sensors, access systems, or automation controllers.

  • Safe and Isolated Switching: Internal relays ensure safe operation and electrical isolation between control signals and powered devices.

The VT12 Relay Module is built to:

  • Power and switch 12V DC devices, such as electronic locks, LEDs, solenoids, fans, alarms, or relays.

  • Integrate with access control, automation, and security systems via dry contact triggers.

  • Simplify low-voltage wiring and control, replacing the need for separate relays or power modules.

  • Support two independent channels, allowing control of multiple devices from a single unit.

Its versatility makes it ideal for use in security systems, building automation, smart home setups, and industrial control panels.
