This low cost, general purpose, USB powered board has  8 opto-isolated, 30VDC/1A high sensitivity (gold contact) signal relays, and fixed screw terminal blocks.

Access to all relay contacts is via fixed screw terminal block connectors  along the edge of the card.  Suitable for a wide range of control and mains voltage power switching purposes .  The card comes with LED relay channel & USB +5V supply status indicators and nylon feet in each corner which will take self tapping screws or allow the cards to be stacked.

There is also a perspex cover available which offers general protection of the card and prevents accidental contact with any of the relay contacts 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.
