SERIES IP440 INDUSTRIAL I/O PACK 32-CHANNEL ISOLATED DIGITAL INPUT MODULE
___________________________________________________________________________________________
- 3 -
•
Programmable Debounce - The event sense input circuitry
includes programmable debounce times for all 32 channels.
Debounce time is the duration of time that must pass before
the input transition is recognized as valid at the ASIC input.
This helps prevent false events and increases noise
immunity.
•
Reverse Polarity Protection - Bipolar inputs are not
polarized and are inherently reverse polarity protected.
•
No Configuration Jumpers or Switches - All configuration
is performed through software commands with no internal
jumpers to configure or switches to set.
•
ASIC Based Monitor - State of the art ASIC (Application
Specific Integrated Circuit from Ziatech Corporation)
provides the 32 channel input and event functionality.
•
Loopback Compatible with IP445 Output Module - The
field side P2 pinouts of this model are directly compatible
with those of the Acromag Model IP445 32-Channel Digital
Output Module for direct closed-loop monitoring of the
output states. The IP440 also shares the same P2 pinout
used on the Acromag non-isolated IP400 40 Channel Input
Module, IP405 40-Channel Output Module, and IP408 32-
Channel I/O Module, for channels 0-31. Likewise, this
model may interface with industry standard I/O panels,
termination panels, and relay racks when used with an
Acromag Model 5025-655 I/O Adaptor Card. However,
since relay racks generally provide isolation, it may be more
efficient to interface with them using the non-isolated IP400
input module.
INDUSTRIAL I/O PACK INTERFACE FEATURES
•
High density - Single-size, industry standard, IP module
footprint. Four units mounted on a carrier board provide up
to 128 isolated input points in a single system slot. Both
VMEbus and ISAbus (PC/AT) carriers are supported.
•
Local ID - Each IP module has its own 8-bit ID PROM which
is accessed via data transfers in the "ID Read" space.
•
8-bit I/O - Port register Read/Write is performed through 8-
bit data transfer cycles in the IP module I/O space.
•
High Speed with No Wait States - Access times for all
data transfer cycles are described in terms of "wait" states--
0 wait states are required for all read and write operations of
this model. See Specifications section for detailed
information.
SIGNAL INTERFACE PRODUCTS
(See Appendix for more information on compatible products)
This IP module will mate directly to any industry standard IP
carrier board (including Acromag AVME9630/9660 3U/6U non-
intelligent VMEbus carrier boards). Additionally, PC carrier
boards are also supported (see Acromag Model APC8600). A
wide range of other Acromag IP modules are also available to
serve your signal conditioning and interface needs.
Note: Since all connections to field signals are made through the
carrier board which passes them to the individual IP modules,
you should consult the documentation of your carrier board to
ensure compatibility with the following interface products.
Cables:
Model 5025-551-X (Shielded Cable), or Model 5025-550-X
(Non-Shielded Cable): A Flat 50-pin cable with female
connectors at both ends for connecting AVME9630/9660, or
other compatible carrier boards, to Model 5025-552
termination panels.
The unshielded cable is recommended for digital I/O, while
the shielded cable is recommended for optimum performance
with precision analog I/O applications. The “-X” suffix of the
model number denotes the length in feet.
Model 5029-900 APC8600 High-Density Cable: A 36-inch
long interface cable that mates the high-density (25mil pitch)
50-pin I/O connectors of the APC8600 PCbus carrier board,
to the high-density connectors on the APC8600 Termination
Panel (described below).
Termination Panels:
Model 5025-552: A DIN-rail mountable panel that provides 50
screw terminals for universal field I/O termination. Connects
to Acromag AVME9630/9660, or other compatible carrier
boards, via flat 50-pin ribbon cable (Model 5025-550-X or
5025-551-X).
Model 5029-910 APC8600 High-Density-to-Screw-Terminal
Termination Panel: This panel converts the high-density
ribbon-cable connectors coming from the APC8600 carrier
board (Acromag cable Model 5029-900) to screw terminals,
for direct-wired interfaces.
Transition Module:
Model TRANS-GP: This module repeats field I/O
connections of IP modules A through D for rear exit from a
VMEbus card cage. It is available for use in card cages
which provide rear exit for I/O connections via transition
modules (transition modules can only be used in card cages
specifically designed for them). It is a double-height (6U),
single-slot module with front panel hardware adhering to the
VMEbus mechanical dimensions, except for shorter printed
circuit board depth. It connects to Acromag Termination
Panel 5025-552 from the rear of the card cage, and to
AVME9630/9660 boards within the card cage, via flat 50-pin
ribbon cable (cable Model 5025-550 or 5025-551).
INDUSTRIAL I/O PACK SOFTWARE LIBRARY
Acromag provides an Industrial I/O Pack Software Library
diskette (Model IPSW-LIB-M03, MSDOS format) to simplify
communication with the board. Example software functions are
provided for both ISAbus (PC/AT) and VMEbus applications.
Software functions of the IP440 are shared by the IP470. All
functions are written in the “C” programming language and can be
linked to your application. For more details, refer to the
“README.TXT” file in the root directory on the diskette and the
“INFO440.TXT” file in the appropriate “IP470” subdirectory off of
“\VMEIP” or “\PCIP”, according to your carrier.
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.
