(Also known as product USB24MxP)  A low-cost, general -purpose, USB powered 24 channel relay board.  Can be commanded via simple ASCII character commands - example programs available for download in several programming languages.  PC, MAC & Linux compatible.  Free shipping (Worldwide). 

Supplied with 120/240VAC, 10Amp power relays.  Suitable for a wide range of control/mains voltage power switching purposes, the PCB tracking is designed to handle 240VAC @ 10amps.

Access to all relay contacts via two part (male/female) side entry, screw terminal blocks mounted  along each edge of the card.  The cards are designed to be stacked, with the side entry connectors allowing for rapid assembly & dismantling.  Power & channel status indicators are visible along one end of the card.

Supplied with nylon feet in each corner which will take self tapping screws or allow the card to be sat on a surface.

The board can be powered from the USB port, (maximum of 8 relays activated at any one time) or the relays can be isolated from the USB +5V (via a jumper link) and the relays powered from an external +5V supply, in which case all relays can be activated.

A perspex cover and base is available which offers general protection of the card and prevents accidental contact with any of the pcb connections or screw terminal connections.  In addition, there is a DIN rail mount/cover option available.

These are industry standard relay boards and products.  High quality, for professional electronic  automation,  connectivity, and control.
