Features red & yellow LEDs to indicate transmission & reception of data, 0V & power disconnect to allow complete isolation of the relays. The board remains the same size as the previous model. Please contact us if you need more details***

This low cost, general purpose, USB powered board has 4 opto-isolated relays and four general purpose digital I/O channels.

The relays are high sensitivity (gold contact) signal relays (30VDC@1A). This board has no terminal block connectors - allowing you to choose and fit your own terminals as needed.

Suitable for a wide range of control and signal switching purposes. The card comes with +5V & relay channel LED status indicators.

Nylon feet are fitted in each corner which will take self tapping screws. They can easily be removed to allow the cards to be mounted on pillars or 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.
