DNx-DIO-430 – 30-Channel solid state relay output board

Channel solid state relay output board


The DNx-DIO-430 are 30-channel, solid state relay boards. The DIO-430 boards are designed for use in a wide variety of switching and digital control applications. Each channel is configured as a standard Form A (SPST) relay and switches voltages up to ±55 VDC or AC waveforms with peaks less than ±55 VDC. Each channel is rated for continuous operation at 400 mA DC or AC rms with a switch resistance of less than 1.5 Ohm (not including external cables).



  • 30 independent Form A (SPST) solid state relays
  • ±55 VDC (maximum operating voltage)
  • 1.5 Ohm resistance (not including cabling)
  • 400 mA continuous load current rating
  • 2 A peak current (<10 mS)
  • 1000 Hz update rate

Each board provides 350 VDC isolation between channels, as well as between the board, cube and other installed I/O boards. Outputs are protected against transients by SMAJ60CA TVS diodes and against over current with a 1 Amp, fast blow fuse.

All relays default to “OFF” on power up/reset. Switching rates up to 1000 Hz are supported.

All connections are made through a convenient 62-pin D connector ensuring no problems obtaining mating cables or connectors. Users may also connect the DNx-DIO-430 boards to our popular DNA-STP-62 screw terminal panel via the DNA-CBL-62 cables. The cables are fully shielded and are available in 2.5, 10 and 20 foot lengths.
