12 V Single-Channel Relay Module

This module provides a single relay channel operated from a 12 V control signal. It is intended for hobbyists and engineers who need to switch a separate load circuit from a low-voltage source such as a microcontroller or sensor output. The compact board mounts easily in enclosures or on prototype plates.

Integration into a control circuit

The relay requires a 12 V supply for its coil and exposes contact terminals for the switched circuit. It frees the controlling logic from directly driving high-current or mains-voltage devices. Wiring must provide the coil voltage and protect the contacts according to the load being switched.

Questions about this item

What is the maximum coil voltage this 12 V single-channel relay can handle continuously?

The module is rated for a 12 V coil supply and is designed for continuous operation at that voltage.

How much heat does the relay generate when the contacts stay closed all day?

The relay dissipates only a small amount of heat from the coil and contact resistance during extended use.
