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.
CARD CAGE CONSIDERATIONS
Refer to the specifications for loading and power
requirements. Be sure that the system power supplies are able
to accommodate the power requirements of the carrier board,
plus the installed IP modules, within the voltage tolerances
specified.
IMPORTANT: Adequate air circulation must be provided to
prevent a temperature rise above the maximum operating
temperature.
The dense packing of the IP modules to the carrier board
restricts air flow within the card cage and is cause for concern.
Adequate air circulation must be provided to prevent a
temperature rise above the maximum operating temperature and
to prolong the life of the electronics. If the installation is in an
industrial environment and the board is exposed to environmental
air, careful consideration should be given to air-filtering.
BOARD CONFIGURATION
Power should be removed from the board when installing IP
modules, cables, termination panels, and field wiring. Refer to
Mechanical Assembly Drawing 4501-434 and your IP module
documentation for configuration and assembly instructions.
Model IP440 digital input boards have no hardware jumpers or
switches to configure.
CONNECTORS
IP Field I/O Connector (P2)
P2 provides the field I/O interface connections for mating IP
modules to the carrier board. P2 is a 50-pin female receptacle
header (AMP 173279-3 or equivalent) which mates to the male
connector of the carrier board (AMP 173280-3 or equivalent).
This provides excellent connection integrity and utilizes gold-
plating in the mating area. Threaded metric M2 screws and
spacers are supplied with the module to provide additional
stability for harsh environments (see Mechanical Assembly
Drawing 4501-434). The field and logic side connectors are
keyed to avoid incorrect assembly.
P2 pin assignments are unique to each IP model (see Table 2.1)
and normally correspond to the pin numbers of the field I/O
interface connector on the carrier board (you should verify this for
your carrier board).

Input channels of this module are divided into four ports of
eight channels each. Channels of a port share a common signal
connection with each other. Isolation is provided between ports
and between each port and the IP logic. With respect to interrupt
generation and events, event polarities may be defined as
positive (low-to-high), or negative (high-to-low) for individual
nibbles (groups of 4 input lines, or half ports). Change-of-State
detection would require 2 input channels--one detecting positive
events, one detecting negative events.
P2 pinouts are arranged to be compatible with similar
industry models. This model is directly loopback compatible with
the Acromag Model IP445 Digital Output Module. Likewise, pin
assignments are identical to those of Acromag Model IP400 40-
Channel Digital Input Boards for channels 0-31. This model may
also interface with industry accepted I/O panels, termination
panels, and relay racks when used with the Acromag Model
5025-655 I/O Adapter Card. Consult the factory for information
on these and other compatible products.
Refer to Drawing 4501-593 for example input connections.
See Drawing 4501-603 for loopback connections to Acromag
Model IP445 Output Modules. Drawing 4501-603 also gives an
example of how to interface the IP440-1 with open-drain TTL
outputs signals.
