AP-12VTRIGGER-INR

Description

Add relay-based trigger control to your audio project

The AP-12VTRIGGER-INR is a 12 V trigger input board with a 3.5 mm jack socket and a relay. It is designed for DIY audio projects that need a relay interface in response to a trigger signal from a preamplifier, receiver or controller.

The incoming trigger operates the relay. Your project uses the relay contacts to implement the required control function, such as a standby command in a compatible control circuit.

Key features

• 12 V trigger input for an audio control project.
• 3.5 mm jack socket for the incoming trigger connection.
• Relay-based interface for integration into your own circuit.

Choosing the right input interface

Choose the INR when your design calls for relay contacts. If your circuit needs an optocoupler interface instead, see the AP-12VTRIGGER-INO. The appropriate choice depends on the circuit you want to control.

Before connecting

• Check the board’s wiring details and the trigger source’s polarity, connector type and available current.
• Verify the relay contact ratings against the voltage and current of the circuit being controlled.
• Check the intended standby or switching behaviour before integrating the board.

This is a control interface. Suitability for switching a particular load depends on the relay ratings and the complete circuit design.
