16-Channel Relay Board, DC Voltage and Pack Options

Bring multiple switched outputs together on one relay interface board for a compatible control project. The 16-channel layout provides a single place to connect the control signals and relay outputs, with separate supply-voltage and pack-quantity options.

Keep multiple relay outputs on one board

• ✅ Organise a larger control project—the sixteen relay channels group multiple switched outputs on one board instead of using a separate module for every output.
• ✅ Check channel activity—the indicator LEDs give you a visible reference when reviewing which channels are being driven.
• ✅ Choose the quantity for your build—one-, three- and five-board packs let you equip a single project or prepare several units.

The board has sixteen relay channels, optocouplers and a microcontroller interface. Supply-voltage options are 5 V, 12 V and 24 V DC; choose the version required by your installation. Approximate dimensions: 17.6 × 9 × 1.7 cm. Confirm the control-signal requirements, supply connection and the ratings marked on the actual relays before wiring loads. A controller, enclosure and power supply are not included.

Board photographs illustrate the layout; the selected voltage and pack quantity determine the supplied modules.

Match the board voltage to your project and choose the pack size you need.
