Interworld Electronics announces the mPCIe-IIRO Series digital I/O cards
from ACCES I/O Products.
Featuring 8- or 4-channel isolated digital input and relay output cards
with Change-of-State (COS) detection in a PCI Express Mini Card format, the
mPCIe-IIRO Series allows digital I/O functionality to be added to modern
embedded computers with a small footprint, where PCI Express Mini Card slots
have become the preferred expansion bus.
The mPCIe-IIRO-8 consists of a type F1 PCI Express Mini Card (mPCIe)
interface board that connects to a mobile-ITX-sized, DB-37M isolation module via
a 230mm cable. Designed to be easily panel-mounted in any application environment,
this module uses the high speed PCI Express bus to transfer digital data to and
from the card. The digital I/O is compatible with 8255 PPI chips, simplifying
programming. The advanced features enabled by the on-board FPGA logic allow the
cards to perform Change-of-State detection and provide interrupt capabilities
that relieve software from polling routines, which can otherwise consume
valuable processing time.
The non-polarised inputs support both AC and DC, and configuration
jumpers allow input filters to be enabled per channel. The isolated inputs
support voltages from 3 to 31 VDC/VAC RMS (40Hz to 10000Hz), as well as
standard 12/24 AC control transformer signals.
Outputs provide access to five Form C (SPDT) and three Form A (SPST)
electromechanical relays capable of 1A continuous-current load.
The mPCIe-IIRO Series is recommended for a variety of applications where
on-board relays are required and the digital inputs must be isolated.
