SERIES IP440 INDUSTRIAL I/O PACK 32-CHANNEL ISOLATED DIGITAL INPUT MODULE
___________________________________________________________________________________________
- 14 -
Input optocouplers of this device are bipolar and accept
voltages in three ranges:
±
(4-18V),
±
(16-40V), and
±
(38-60V),
DC or AC peak. The optocouplers connect directly to a digital
ASIC I/O controller that provides the I/O read/write functionality,
interrupt handling, and debounce control.
LOGIC/POWER INTERFACE
The logic interface to the carrier board is made through
connector P1 (refer to Table 2.2). P1 also pr5V to power
the module (the
±
12V lines are not used). Not all of the IP logic
P1 pin functions are used.
A programmable logic device installed on the IP Module
provides the control signals required to operate the board. It
decodes the selected addresses in the I/O, Interrupt, and ID
spaces and produces the chip selects, control signals, and timing
required by the control registers, as well as, the
acknowledgement signal required by the carrier board per the IP
specification. It also stores the interrupt vector and controls
whether event interrupts will drive the carrier board interrupt
request line.
The ID PROM (read only) is implemented in the PLD installed
on the IP module and provides the identification for the individual
module per the IP specification. The ID PROM & configuration
and control registers are all accessed through an 8-bit data bus
interface to the carrier board.
5.0 SERVICE AND REPAIR
SERVICE AND REPAIR ASSISTANCE
Surface-Mounted Technology (SMT) boards are generally
difficult to repair. It is highly recommended that a non-functioning
board be returned to Acromag for repair. The board can be easily
damaged unless special SMT repair and service tools are used.
Further, Acromag has automated test equipment that thoroughly
checks the performance of each board. When a board is first
produced and when any repair is made, it is tested, placed in a
burn-in room at elevated temperature, and retested before
shipment.
Please refer to Acromag's Service Policy Bulletin or contact
Acromag for complete details on how to obtain parts and repair.
PRELIMINARY SERVICE PROCEDURE
Before beginning repair, be sure that all of the procedures in
Section 2, Preparation For Use, have been followed. Also, refer
to the documentation of your carrier board to verify that it is
correctly configured. Replacement of the module with one that is
known to work correctly is a good technique to isolate a faulty
module.
CAUTION: POWER MUST BE TURNED OFF BEFORE
REMOVING OR INSERTING BOARDS
Acromag’s Application Engineers can provide further
technical assistance if required. When needed, complete repair
services are also available from Acromag.

Max Component Height........0.314 inches (7.97 mm).
Connectors:
P1 & P2 ..............................IP logic (P1) & field (P2) interface
connectors -.50-pin female
receptacle header (AMP 173279-
3 or equivalent).
Power:
+5 Volts (
±
5%)....................90mA, Typical (all inputs low);
120mA, Typical (all inputs high);
160mA, Maximum.
±
12 Volts (
±
5%) from P1......0mA Maximum (Not Used).
Isolation......................................Logic and field connections are
optically isolated (see INPUT
specifications). Individual ports
are also isolated from each
other. However, input lines of
individual ports share a common
connection and are not isolated
from each other. Separate port
commons are provided to
facilitate port-to-port isolation.
Logic and field lines are isolated
from each other for voltages up
to 250VAC, or 354V DC on a
continuous basis (unit will
withstand a 1500V AC dielectric
strength test for one minute
without breakdown). This
complies with test requirements
outlined in ANSI/ISA-S82.01-
1988 for the voltage rating
specified.
Isolation Spacing........................Printed circuit board minimum
isolation spacings are as follows:
Port-to-Logic - 0.025” Minimum;
Port-to-Port - 0.015” Minimum.
These clearances apply to inner
layer foil spacings (outer layer
foil spacings are greater).
Resistance to RFI.......................No data upsets occur for field
strengths up to 10V per meter at
27MHz, 151MHz, & 460MHz per
SAMA PMC 33.1 test
procedures.
Resistance to EMI......................Unit has been tested with no
data upsets under the influence
of EMI from switching solenoids,
commutator motors, and drill
motors.
ESD Protection...........................Field input lines are protected
from ESD voltages to
±
4KV,
typical.
