ADLINK PCI-7251 - Manual (Page 10)

2 Introduction
1.1 Features
The PCI-725X Relay Actuator and D/I cards provide the following
advanced features:
X 32-bit PCI-Bus, Plug and Play (PCI-7250, LPCI-7250)
X 32-bit CompactPCI
®
Bus, Plug and Play (cPCI-7252)
X 8 relay actuator outputs
X 8 opto-isolated digital inputs (PCI-7250, LPCI-7250,
LPCIe-7250)
X x1 lane PCI Express Interface (LPCIe-7250)
X 16 opto-isolated digital inputs (cPCI-7252)
X Onboard 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: PCI-7251 is the extension module of the PCI-7250. Each
PCI-7251 card provides an additional 8 relay outputs and 8
photo isolated inputs. Up to three PCI-7251 cards can be at-
tached to one PCI-7250 card to provide 32 relay outputs and
32 photo isolated inputs.
