128-CH Isolated DI & 128-CH Isolated DO Card
cPCI-7452
Introduction
The ADLINK cPCI-7452 is a 256-CH extra-high-density opto-isolated digital input and output card. It provides a
robust 2500 VRMS isolation protection, suitable for most industrial applications. The wide input range of the cPCI-7452
makes it easy to sense the status of external devices. The cPCI-7452 also features a wide output range from 5 to 35 V,
suitable for driving relays and use in industrial automation applications. The cPCI-7452 provides sink drive outputs. The
cPCI-7452 provides Change-of-State interrupt on all digital input channels, simplifying configuration and management.
