USB4PRMx (fitted with four 240VAC/10A relays)

USB4PRMx  - shown with perspex cover fitted (CoverUSB4Mx)

This low cost, general purpose, USB powered card has  4 opto-isolated relays  and four general purpose digital I/O channels.  The relays and PCB tracking are designed to handle 240VAC@10A.  Access to all relay contacts and the 4 DIO channels 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, it also offers screw terminal access to the USB power connections for possible onward powering/use in your target system .  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.

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).
