DIO24MxHdr-25D Connects directly to our USBDIO24, or NI DIO24/6503 Digital I/O DAQ card products via standard 50 pin I/O header connector.

  • Provides access to all relay contacts via two 25 way D terminals and an IDC header. The IDC header can be used with an IDC cable to another 25 way D connector.

  • Relay activation/control is via logic level digital signals which connect via standard 50 pin I/O header connector

  • All channels can be configured as either inputs or outputs via onboard links

  • Opto-isolated digital control inputs.  Provides voltage isolation of 2500V AC

    (Can also be controlled by Arduino or Pi)

  • LED channel status indication with opto-isolation options

  • Relays can be activated via any suitable digital (5V) input signal

  • Requires external 12V DC power supply (800 mA max per relay card (if all relays are switched on), PSU connects via DC jack

    These are industry standard relay boards and products.  High quality, for professional electronic  automation,  connectivity, and control.

    Easydaq products are used in research and education, security, industrial applications, power and energy management,  motor and device  control. There are uses across various industries, including  maritime , rail,  automotive, automation, measuring and calibration, agriculture , medical, sanitation, light and power solutions, fire protection, defence, security, and many more.
