USB8PR2 (fitted with eight 10A relays)

USB8PR2 (fitted with four 10A relays & 2 part screw terminal blocks) - shown with perspex cover fitted

This low cost, general purpose, USB powered card has  8 opto-isolated relays  and is available with a choice of either 240VAC/10A power or 30VDC/1A high sensitivity (gold contact) signal relays, and the option of either fixed or two-part (male/female) 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, or signal 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.

Compatible with Windows 98SE/ME/2000/XP/Vista, Windows 7, Windows CE, MacOSX and Linux platforms.

Available with LabVIEW, LabWindowsCVI, VB, VC, C#, Java, VEE, & Delphi examples available (click on the 'downloads' button below).
