ESD Precautions
Integrated circuits on computer boards are sensitive to static
electricity. To avoid damaging chips from electrostatic
discharge, observe the following precautions:
! Do not remove boards or integrated circuits from their anti-static
packaging until you are ready to install them.
! Before handling a board or integrated circuit, touch an unpainted
portion of the system unit chassis for a few seconds. This helps
to discharge any static electricity on your body.
! Wear a wrist-grounding strap, available from most electronic
component stores, when handling boards and components.

iv
Unpacking
The AX5420P/AX5425P is packed in an anti-static bag. The
PCI Bus board has components that are easily damaged by
static electricity. Do not remove the anti-static wrapping until
proper precautions have been taken. Safety instructions in front
of this User's Manual describe anti-static precautions and
procedures.
After unpacking the PCI Bus board, place it on a raised surface
and carefully inspect the board for any damage that might have
occurred during shipment. Ground the board and exercise
extreme care to prevent damage to the board from static
electricity.
Integrated circuits will sometimes come out of their sockets
during shipment. Examine all integrated circuits, to ensure that
they are firmly seated. The AX5425P(0) PCI Bus interface DI/O
Board package includes the following:
!
AX5420P/AX5425P Board
! AX5003 Extension Board, for AX5425P only
! Flat cable 40p 45cm x 1, for AX5425P only
! AS59099 DAC Driver CD
!
AX5425P(0) user's manual
! Warranty card
Make sure that all of the items listed above are present.
What To Do If There Is A Problem
If there are damaged or missing parts, contact your supplier
and/or dealer immediately. Do not attempt to apply power to the
board if there is damage to any of its components.

Introduction
1.1 General Description
The AX5425P/AX5420P are PCI-isolated/Relay DIO cards
providing 16 (AX5425P) / 8 (AX5420P) opto-isolated digital
inputs and 16 (AX5425P) / 8 (AX5420P) Relay actuators
outputs. AX5425P is a 16 opto-isolated and 16 Relays card.
AX5420P is an 8 opto-isolated and 8 Relays card.
The board interface allows its plugging into any PCI slot of an
IBM™ PC/AT or compatible computer with PCI bus .The relays
switch many load that cannot be controlled by digital lines
directly. The opto-isolated digital inputs are suitable for
monitoring device ON/OFF status and alarms or sensors with
discrete outputs in noisy environments. Besides monitoring DC
inputs (non-polarized), the board can also be used to sense AC
inputs.
From the 16 electromechanical relays, 10 relays are FORM C
(Normally open, Normally closed and Common) and 6 are
FORM A (Normally open and Common). The contacts for Relay
1 through Relay 8 are rated at 3A at 120VAC or 24VDC with
resistive load while the contacts for Relay 9 through Relay 16
are rated at 3A at 120VAC or 24VDC with resistive load.
The opto-isolated inputs are not polarity sensitive, and can be
driven from DC or AC control voltages. The isolation voltage is
guaranteed at 1000v so that common-mode voltages and
voltage spikes that often occur in industrial and research
environments are safely isolated from the computer with the
AX5425P and AX5420P.

You may configure the relay outputs and isolated digital input.
When the corresponding bit is in the low (0) state, the NC
(Normally Closed) contact is connected inside the relay to the
CM (Common) contact. When the corresponding bit is in high (1)
state, the NO (Normally Open) contact is connected to the CM
contact. All relay contacts and isolated input lines are built in
two I/O connectors, which are accessible from the expansion
slot, rear panel of the PC.
