implement self-test or fault diagnosis, since inherent loopback
can be used to detect open output switches or shorts.
•
High Voltage Inputs & Outputs
- Inputs and outputs are
rated to 60VDC. I/O channels are non-isolated and share a
common connection.
•
High Impedance Inputs
- High impedance inputs minimize
loading of the input source and input current.
•
No Configuration Jumpers or Switches
- All configuration is
performed through software commands with no internal
jumpers to configure or switches to set.
•
Power Up & System Reset is Failsafe
- For safety, the
outputs are always OFF upon power-up and cleared after a
system reset. Unlike some competitive units, output gate
pulldowns are included to ensure that the outputs do not turn
on momentarily when output load power is applied with no
power to the IP module.
•
True Logic
- Outputs operate using True-Logic
(1=ON/SWITCH CLOSED, 0=OFF/SWITCH OPEN).
•
Low R
dsON
(0.2
Ω
Maximum)-
Low output drain-to-source ON
resistance ensures TTL logic-low compatibility at high currents
and reduces power dissipation.
•
High Output Current
- individual output channels may sink up
to 1A DC continuous (up to 10A total, all channels combined),
or 312mA DC (with all 32 channels ON). No deration of
maximum output current is required at elevated ambient
temperatures.
PCI MEZZANINE CARD INTERFACE FEATURES
•
High density -
Single-width PMC Target module.
•
Field Connections –
All digital inputs/outputs (channels 0 –
31) and common connections are made through a single 50-pin
SCSI-2 front panel I/O connector.
•
16-bit I/O
- Channel register Read/Write is performed through
through 32-bit, 16-bit or 8-bit data transfer cycles in the PCI
memory space.
•
Compatibility
– IEEE P1386.1 compliant PMC module which
complies to PCI Local Bus Specification Revision 2.2.
Provides one multifunction interrupt. 5V signaling compliant
and 3.3V signaling tolerant.
SIGNAL INTERFACE PRODUCTS
(See Appendix for more information on compatible products)
This PMC Module will mate directly to any standard PMC
carrier/CPU board that supports one single width PMC mezzanine
module. Once connected, the module is accessed via a 50 pin front
panel connector.
The cables and termination panels, described in the following
paragraphs, are also available. For optimum performance with the
PMC408 digital I/O module, use of the shortest possible length of
shielded I/O cable is recommended.
Cables:
Model 5025-187 (SCSI-2 to Flat Ribbon Cable, Shielded): A
round 50 conductor shielded cable with a male SCSI-2
connector at one end and a flat female ribbon connector at the
other end. The cable is used for connecting the PMC408
module to Model 5025-552 termination panels.
Termination Panel:
Model 5025-552: DIN-rail mountable panel provides 50 screw
terminals for universal field I/O termination. Connects to
Acromag PMC408, via SCSI-2 to Flat Ribbon Cable, Shielded
(Model 5028-187).
PMC MODULE ActiveX CONTROL SOFTWARE
Acromag provides a software product (sold separately)
consisting of PMC module ActiveX (Object Linking and Embedding)
controls for Windows 98, 95
®
, ME, 2000 and Windows NT
®
compatible application programs (Model PMCSW- ATX, MSDOS
format). This software provides individual controls that allow
Acromag PMC modules to be easily integrated into Windows
®
application programs, such as Visual C++
™
, Visual Basic
®
,
Microsoft
®
Office
®
97 applications and others. The ActiveX
controls provide a high-level interface to PMC modules, eliminating
the need to perform low-level reads/writes of registers, and the
writing of interrupt handlers—all the complicated details of
programming are handled by the ActiveX controls. These functions
consist of an ActiveX control for each Acromag PMC module.
PMC MODULE VxWORKS SOFTWARE
Acromag provides a software product (sold separately)
consisting of PMC module VxWorks
®
libraries. This software
(Model PMCSW-API-VXW, MSDOS format) is composed of
VxWorks
®
(real time operating system) libraries for all Acromag
PMC modules. The software is implemented as a library of “C”
functions which link with existing user code to make possible simple
control of all Acromag PMC modules.
2.0 PREPARATION FOR USE
UNPACKING AND INSPECTION
Upon receipt of this product, inspect the shipping carton for
evidence of mishandling during transit. If the shipping carton is
badly damaged or water stained, request that the carrier's agent be
present when the carton is opened. If the carrier's agent is absent
when the carton is opened and the contents of the carton are
damaged, keep the carton and packing material for the agent's
inspection.
For repairs to a product damaged
in shipment, refer to the Acromag
Service Policy to obtain return
instructions. It is suggested that
salvageable shipping cartons and
packing material be saved for future
use in the event the product must be
shipped.
This board is physically protected with
packing material and electrically
protected with an anti static bag during
shipment. However, it is recommended
that the board be visually inspected for
evidence of mishandling prior to
applying power.
The board utilizes static sensitive components and should only be
handled at a static-safe workstation.
