32-CH Isolated DIO PCI Cards

Key Features
  • Supports a 32-bit 5 V PCI bus
  • 16-CH isolated digital inputs & 16-CH isolated digital outputs (PCI-7230)
  • 32-CH isolated digital inputs (PCI-7233)
  • 32-CH isolated digital outputs (PCI-7234)
  • 5000 VRMS optical isolation (PCI-7230 & PCI-7233)
  • Sink current up to 500 mA on each isolated output


Tech Square,s PCI-723X series are 32-CH isolated input and/or output cards which provide a 2,500 V optical isolation protection. The wide input range of the PCI-7230 and PCI-7233 makes it easy to sense the status of external devices. The non-polarity characteristic is suitable for a wide variety of industry applications. The PCI-7230 and PCI-7234 devices also feature a wide output range from 5 to 35 V, which is suitable for relay driving and industrial automation applications. The PCI-7234P provides current-source output capability. The PCI-7230 and PCI-7233 also provide two interrupt sources on digital input channels. The PCI-7233 also features a change-of-state (COS) function that generates an interrupt when any digital input changes its state.
