Pre-assembled & tested relay card stacks - using our range of 24-channel relay cards providing a low cost solution for connecting large numbers of relays in a variety of configurations with rapid connect/disconnect/swap-over option. Control the boards with the USB interface of the USBDO96 which is included.

  • Convenient pre-assembled & tested stack of relays in relatively small cubic area, includes ribbon cables &  USBDO96 + Adapter cards

  • Available for use with any relay cards from our DO24PRMx product range

  • 2 part (male/female) relay card screw terminal blocks allow the stack to be rapidly assembled & connected or swapped over in a maintenance situation.

  • 5V DC power supply required to power the relay cards (USBDO96 card is powered from the USB port)

  • Each relay card requires 5VDC @ approx 1200 mA if all relays are switched on.  (Each relay requires approx 45mA)

  • PSU connects via 2 part screw terminal block

  • CЄ & RoHS compliant

    (also control via PC, MAC, Raspberry Pi)

Stacks are pre-assembled modules using relay cards from our DO24PRMx range of 24 channel relay cards.  Up to four (24 channel) relay cards can be used per stack assembly.
