PCI-7251Expansion board with 8 relays and 8 isolated inputs for PCI-7250
- Manufacturer
PCI-7251 is a relay and isolated digital input expansion board for computers with a PCI bus, meant to add command and reading channels to a system already fitted with a PCI-7250.
The contacts switch 120 V AC at 0.5 A and 24 V DC at 1 A, with status LEDs reporting the opening and closing of each relay. The isolation voltage of the inputs is 5000 VRMS.
