24 V 8-Channel Relay Module

This 24 V relay board provides eight optically isolated channels for switching AC or DC loads from a low-voltage controller. Each channel uses a silver-alloy contact rated at 4 amps and a KF301 connector for secure wiring. The module accepts a 5 V supply drawing 4 mA quiescent and 65 mA when active, with a trigger threshold of 0–2 V at 2 mA. It suits hobbyists and engineers adding mains-level control to microcontroller projects.

DIN-Rail Mount with KF301 Connectors

The DIN-rail footprint lets the board snap onto standard rails inside cabinets or enclosures, keeping wiring tidy and vibration-resistant. Optocoupler isolation separates the control side from the 220 V load side, protecting the host controller from transients. Both high-level and low-level trigger modes are supported, giving flexibility for different logic conventions. No external driver circuitry is required for the eight independent channels.

Ten Single-Channel Shields Included

The package supplies ten individual 1-channel 5 V relay shields alongside the main 8-channel board. These shields can be distributed across a project for remote switching points or used as spares during development. Each shield mirrors the same isolation and trigger characteristics, allowing consistent behaviour throughout the system. The extra modules simplify prototyping and reduce the need for separate component orders.

Questions about this item

How many amps can each of the 8 channels switch continuously?

Each channel is rated for 4 amps using silver-alloy contacts on the Kf301 connector.

What is the module's current draw when all 8 relays are energised?

The board draws 65 mA total while operating from a 5 V supply.

Which supply voltage must the buyer provide for the control side?

A 5 V DC source is required to drive the optocoupler-isolated inputs.
