This low cost, general purpose, USB powered board has  16 relays + 8 general purpose DIO channels + 8 channels that can be selected as either relay or DIO channels (via onboard links).  Relays & PCB tracking are designed to handle 240VAC@10A.  Suitable for a wide range of control and mains voltage power switching purposes, it also offers screw terminal access to the USB power connections for possible onward powering/use in your target system.

DIO channels are normal logic level signals (+5V max) and can supply up to 20mA per channel.  Access to all relay contacts and DIO channels is via 2 part (male/female) screw terminal block connectors positioned  along two edges of the card. 

The board comes with +5V & relay/DIO channel LED status indicators.  The USB +5V will support up to 8 relays being activated simultaneously.  *An external +5V PSU is required if more than 8 relays need to be activated at the same time,  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 (see below) 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.
