PCI-7258
32-CH PhotoMos Relay Outputs & 2-CH Isolated DI Card
Introduction
ADLINK's PCI-7258 is a 32-CH PhotoMos relay and 2-CH isolated digital input card. The 32 PhotoMos relay
outputs on the PCI-7258 can switch external devices, including those requiring high input voltage or AC/DC signal
at different levels. PhotoMos relays feature long mean-time-between-failure (MTBF) coming from the solid-state
process. This makes the PCI-7258 ideal in various applications, such as semiconductor applications, telecommunications,
instrumentations, medical equipments, and machine automation.
The 2-CH isolated digital inputs on the PCI-7258 can sense the status of external inputs. The PCI-7258 can generate
an interrupt when one or both inputs change from low to high. Using these interrupts well can release your
computer from a heavy burden in dealing with digital input data.
