The PCI-743X series is a 64 channel high-density digital input/output card that provides highly reliable 2500 V isolation protection, suitable for most industrial applications. The wide input range of PCI-7432 and PCI-7433 makes it easy to sense the status of external devices. The PCI-743X series has multiple models, such as the standard version with an input range of 0 to 24 V and the HIR version with a high input range of 0 to 50 V. PCI-7433 ALC is designed specifically for AC power testing systems. PCI-7432 and PCI-7434 have a wide output range of 5 to 35 V, suitable for relay drive and industrial automation applications. PCI-7432 and PCI-7433 also provide two easily configurable interrupt sources on the digital input channel.
