SERIES IP440 INDUSTRIAL I/O PACK 32-CHANNEL ISOLATED DIGITAL INPUT MODULE
___________________________________________________________________________________________
- 15 -
INPUTS
Input Channel Configuration.......32 Optically isolated bipolar
inputs. For DC or AC voltage
applications within specified
range limits.
Isolation Medium........................Photo-transistor optocoupler,
Siemans SFH628A-4 or
equivalent. UL & VDE rated for
isolation voltages up 400V DC or
AC rms (optocoupler only).
Bipolar Input Voltage Range.......AC or DC Volts peak, per model
number:
±
4V to
±
18V (Model
IP440-1);
±
16V to
±
40V (Model
IP440-2);
±
38V to
±
60V (Model
IP440-3). Range is determined
by value of the input current
limiting SIP resistors installed on
the module (R5, R6, R7, R8).
Input Threshold..........................Refer to Table below. The
IP440-1 model may be used to
interface with open-drain TTL
outputs when used with an
appropriate pullup to +5V (see
Drawing 4501-603).
IP440 INPUT RANGE ON Threshold Voltage
Range (AC or DC Peak) MIN TYP MAX
-1 ± 4V to ±18V ±1V ±2V ±4V
-2 ±16V to ±40V ±4V ±6.4V ±16V
-3 ±38V to ±60V ±8V ±12.9V ±38V
Input Hysteresis.........................80mV Typical.
Input Capacitance......................45pF Typical.
Turn-On Time............................Measured to point of positive
event interrupt detection
(IntReq0 pulled low) - 15us
Typical (25
°
C) for a 0 to
threshold input step. Time
decreases as magnitude of the
step is increased above
threshold.
Turn-Off Time.............................Measured to the point of
negative event interrupt detection
(IntReq0 pulled low) - 35us
Typical (25
°
C) for a threshold to
0V input step. Time increases
as magnitude of the step value is
increased from the threshold.
Input Debounce..........................Each input includes debounce
circuitry with variable debounce
times. Debounce times are
programmable and derived from
the 8MHz system clock, in
combination with the debounce
duration register value.
Debounce times are applied at
the ASIC input and do not
include optocoupler delay time.
Debounce values of 3-4us, 48-
64us, 0.75-1ms, and 6-8ms may
be configured. Note that the
debounce clock must be enabled
via the Debounce Select register
to utilize debounce.
Interrupts....................................32 channels of interrupts may be
configured for high-to-low, low-to-
high, and change-of-state (two
inputs required) event types.
Forward Voltage Drop................1.1V Typical, 1.5V Maximum
(Diode) + I*R. Series input
current-limiting resistors are 2.2K
(IP440-1), 12K (IP440-2), or 27K
(IP440-3) and installed on board.
Input Current..............................Varies per model number and
input signal voltage level. For
Model IP440-1, the current is
computed by dividing the signal
level minus 1.5V, by its current
limiting resistor (2200
Ω
for
IP440-1, 12000
Ω
for IP440-2,
and 27000
Ω
for IP440-3).
INDUSTRIAL I/O PACK COMPLIANCE
Specification..............................This module meets or exceeds
all written Industrial I/O Pack
specifications per revision 0.7.1.
Electrical/Mechanical Interface..Single-Size IP Module.
IP Data Transfer Cycle Types Supported:
Input/Output (IOSel*)............D16 or D08 least significant byte
read/write of port data.
ID Read (IDSel*)...................32 x 8 ID PROM read on
D0..D7.
Interrupt Select (INTSel*).....8-bit word (D08) read of Interrupt
Vector Register contents.
Access Times (8MHz Clock):
All Read/Write Cycles..........0 wait states (250ns cycle).
APPENDIX
CABLE: MODEL 5025-550-x (Non-Shielded)
MODEL 5025-551-x (Shielded)
Type: Flat Ribbon Cable, 50-wires (female connectors at both
ends). The ‘-x’ suffix designates the length in feet (12 feet
maximum). Choose shielded or unshielded cable according
to model number. The unshielded cable is recommended for
digital I/O, while the shielded cable is recommended for
optimum performance with precision analog I/O applications.
Application: Used to connect a Model 5025-552 termination
panel to the AVME9630/9660 non-intelligent carrier board A-
D connectors (both have 50-pin connectors).
Length: Last field of part number designates length in feet (user-
specified, 12 feet maximum). It is recommended that this
length be kept to a minimum to reduce noise and power loss.
Cable: 50-wire flat ribbon cable, 28 gage. Non-Shielded cable
model uses Acromag Part 2002-211 (3M Type C3365/50 or
equivalent). Shielded cable model uses Acromag Part 2002-
261 (3M Type 3476/50 or equivalent).
Headers (Both Ends): 50-pin female header with strain relief.
Header - Acromag Part 1004-512 (3M Type 3425-6600 or
equivalent). Strain Relief - Acromag Part 1004-534 (3M Type
3448-3050 or equivalent).
Keying: Headers at both ends have polarizing key to prevent
improper installation.
Schematic and Physical Attributes: For Non-Shielded cable
model, see Drawing 4501-462. For Shielded cable model,
see Drawing 4501-463.
Shipping Weight: 1.0 pound (0.5Kg) packaged.
