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.  There is a choice of two relay types, either 240VAC/10A power or 30VDC/1Amp high sensitivity (gold contact) signal relays.  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 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, VB, VC, C#, Java, VEE, & Delphi examples available (click on the 'downloads' button below).

USB4PRMx  - shown with DIN rail base & perspex cover fitted (CoverUSB4MxDIN)

• Available with LabView, Visual Basic, Visual C, C#, Java, VEE or Delphi example programs/library files
• Uses same software interface & drivers as used in our existing range of USB and serial port cards - previously developed code can be reused
• Simple text commands mean the card can be controlled with commands input from terminal emulation programs (such as Windows HyperTerminal)
• Two relay options available, either 10A/240V power, or 1A/30V high sensitivity (gold contact) signal relays.  PCB tracking will handle 10 Amps.  Above datasheet link gives full details/spec for the relay types available for this card.
• Relays are SPDT, Form C, changeover type, with N/O, COM and N/C contacts taken to the screw terminal blocks along each side of the card
• Opto-isolated - USB isolation from relays to 2500V AC (rms)
• LED status indicators for USB connection/power and relay activation status
• Relay contact resistance 100mOhms Max
• Relay Operate 12mS /release time 7mS Max (inc software overhead)
• All relay contacts taken to screw terminal blocks
• DIO channels are TTL level digital voltages, each DIO channel can source 25mA
• USB 0V & +5V supply voltages are taken to screw terminal blocks for possible onward use in (or powering of) target application
• Removable link gives the option of powering the relays from an external 5V PSU (connects via an edge mounted screw terminal block)
