IMPORTANT SAFETY CONSIDERATIONS
It is very important for the user to consider the possible adverse
effects of power, wiring, component, sensor, or software failures
in designing any type of control or monitoring system. This is
especially important where economic property loss or human life
is involved. It is important that the user employ satisfactory
overall system design. It is agreed between the Buyer and
Acromag, that this is the Buyer's responsibility.
1.0 GENERAL INFORMATION
The Industrial I/O Pack (IP) Series IP440 module provides 32
channels of isolated digital inputs for interfacing to the VMEbus or
ISAbus, according to your carrier board. Four units may be
mounted on a single carrier board to provide up to 128 inputs per
system slot. Inputs of this module are bipolar and can be used to
sense positive or negative voltages in 3 ranges according to the
model:
MODEL INPUT RANGE THRESHOLD
IP440-1 ±4V to ±18V DC or AC peak ±4V Max
IP440-2 ±16 to ±40V DC or AC peak ±16V Max
IP440-3 ±38 to ±60V DC or AC peak ±38V Max
MODEL OPERATING TEMPERATURE RANGE
IP440-X 0 to +70°C
IP440-XE -40 to +85°C
The inputs normally function as independent input level
detectors without interrupts. However, each input line includes
built-in event sense circuitry with programmable polarity,
debounce, and interrupt support. Inputs also include hysteresis
for increased noise immunity. The IP440 utilizes state of the art
Surface-Mounted Technology (SMT) to achieve its wide
functionality and is an ideal choice for a wide range of industrial
I/O applications that require a high-density, highly reliable, high-
performance interface at a low cost.
KEY IP440 FEATURES
•High Channel Count - Provides programmable monitor and
control of 32 optically-isolated input points. Four units
mounted on a carrier board provide 128 isolated input points
in a single VMEbus or ISAbus (PC/AT) system slot.
•High-Speed/0 Wait States - No wait states are required for
all read/write cycles (all cycles complete in 250ns) and hold
states are supported.
•Wide Range Bipolar Input Voltage - Three model ranges
provide interface capability for bipolar voltages from ±4 to
±60V DC or AC peak (see Specifications section).
•Optically Isolated - Individual bipolar opto-couplers provide
isolation. There are four groups (ports) of 8 channels each
which include separate port commons to ensure port-to-port
isolation. Individual ports are isolated from each other and
from the logic.
•Programmable Polarity Event Interrupts - Interrupts are
software programmable for positive (low-to-high) or negative
(high-to-low) input level transitions on all 32 channels.
Using two channels per input, change-of-state transitions
may also be configured.
•Input Hysteresis - Isolated inputs include hysteresis for
increased noise immunity.
