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.
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 FPGA 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.
Loopback Compatible with AP445 Output Module - The field side
of this model are directly compatible with those of the Acromag
Model AP445 32-Channel Digital Output Module for direct closed-
loop monitoring of the output states. The AP440 also shares the
same pinout used on the Acromag non-isolated AP408 32-Channel
I/O Module, for channels 0-31.
Module Health Monitoring- On board supply voltages and FPGA
junction temperature can be monitored for out of tolerance
conditions via XADC registers.
1.3.3 Key Features PCIe Interface
PCIe Bus – The AP module includes a PCI Express Generation 1
interface operating at a bus speed of 2.5 Gbps with one lane in each
direction.
Compatibility – PCI Express Base Specification v2.1 compliant PCI
Express Endpoint.
