2Introduction
1.1 Features
The PCI-725X Relay Actuator and D/I card provides the following
advanced features:
X 32-bit PCI-Bus, Plug and Play (PCI-7250)
X 32-bit CompactPCI® Bus, Plug and Play (cPCI-7252)
X 8 relay actuator outputs
X 8 opto-isolated digital inputs (PCI-7250)
X 16 opto-isolated digital inputs (cPCI-7252)
X LED indicators to show energized relays
X Jumper selectable AC-filter/non-AC-filter input signals
X On-board relay driving circuits
X On-board digital input signal conditioning circuits
Note: The PCI-7251 attaches to a PCI-7250 card. Each PCI-7251
card provides an additional 8 relay output and 8 photo isolat-
ed input signals. Up to three PCI-7251 cards can be attached
to one PCI-7250 card to provide 32 relay output signals and
32 photo isolated inputs signals.
1.2 Applications
X Industrial ON/OFF control
X External high power relay driving signal switching
X Laboratory automation
X Industrial automation
X Switch contact status sensing, limit switch monitoring,
X Useful with A/D and D/A cards to implement a data acquisi-
tion & control system
