These low-cost, general purpose, boards are fitted with 8 opto-isolated relays  and designed to be operated/controlled by normal digital input voltage signals from a designers own digital hardware or existing DIO/DAQ cards. 

Available with high sensitivity, gold contact signal relays (Max 30VDC @ 1Amp) and the option of either fixed or two-part (male/female) screw terminal blocks.

Access to all relay contacts is via a fixed screw terminal block connectors  along the edge of the card.  Suitable for a wide range of control and signal switching purposes .  The card comes with LED relay channel & +5V supply status indicators and nylon feet in each corner which will take self tapping screws or allow the cards to be stacked.  The card requires a +5V DC supply (Max current approx 750mA with all relays activated).

There is 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.
