USB16PRMxN - 8 channel relay + 8 relay or DIO card + 8 DIO  (240VAC @ 10A)

This low cost, general purpose, USB powered card has  8 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, or signal 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 card 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.

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).

*Note: Onboard link must be removed before connecting an external +5V supply to the USB16PRMxN.

• Low cost, USB powered module -  USB1.1 or 2 compatible (Type B USB connector)
• 8 relays (rated at 240VAC@10A ), 8 general purpose logic level DIO channels (25mA source current each) and 8 user selectable channels which can be connected in any combination as either relays or DIO channels (via onboard link header connectors - for example 12 relays and 12 DIO channels, or 16 relays and 8 DIO channels etc)
• Compatible with Windows 98SE/ME/2000/XP/Vista, Windows 7, Windows CE, MacOSX and Linux platforms
• 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)
• USB interface chip has a unique (factory set) serial number programmed into it.  The card will be automatically assigned the next available USB port number when first connected to your PC.  The USB port number can be manually changed using the device manager if needed
• Relays are rated at 240VAC@10A and 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
• See above datasheet link for details/spec for the relay type fitted to this card.
• LED status indicators for USB connection/power and relay activation/DIO status
• The 8 general purpose DIO channels can be isolated from LED indicators if required (via onboard links)
• 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 normal TTL logic level digital voltages (5VDC max).  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
• USB16PRMxN requires external +5V PSU if more than 8 relays are activated simultaneously (see below)
• Supplied with nylon feet (will take self tapping crews).  Corner mounting holes allow cards to be stacked if required
• Clear, protective cover/base, and also DIN rail mountable base & cover options available (see below)
• CЄ & RoHS compliant, BS9001:2000 manufacture
• Free shipping on this product (Worldwide)
