Introduction
The PCI-8056 is an ideal “system board” for PC
based application in industrial controls. It has isolated,
32 D/I and 24 D/O. All DI’s can also be configured as
interrupt inputs. In addition, there is a 2K bytes
battery backup RAM on board, providing nonvolatile
memories for the entire PC based system.
Furthermore, a programmable timer interrupt is
offered from this board which can act as the system
“tick” for user’s real time partition of all the software
modules in the system.
On-board Battery Backup RAM
The design, on-board battery backup RAM, supports
a storage unit that data can remain stored safely
without the risk of losing it, and assures the data
security while PC shuts down or loses the power.
While working on it, users can save important data or
key parameter in advance, or constantly update and
save output values in RAM that let users always
obtain latest figures; furthermore, save several ones
of multiple data.
Applications
Š PC-based Programmable Logic Controls
Š Isolated digital input sensing
Š Process status monitoring
Š Industrial ON/OFF control
Š Laboratory automation
