Features
- Powerful and Versatile Controller
The I-7188XA data acquisition controller is designed for industrial applications and can be used to replace PC or PLC devices in harsh environments. The I-7188XA controller is designed for palm-size embedded systems that require high reliability, PC-compatibility, and compactness at a reasonable price. The controllers can be integrated into an OEM product as a processor core component. By building your product around I-7188XA controller, you reduce the time from design to market introduction, cut development costs, minimize technical risks, and deliver a more reliable product.
Depending on the type of embedded firmware programs that are being developed, and which I/O Expansion Board, the I-7188XA can be used as a single versatile controller.
I/O Expansion Bus and Expansion Board
The I-7188XA supports an I/O expansion bus. The I/O expansion bus can be used to implement various I/O functions such as D/I, D/O, A/D, D/A, Timer/Counter, UART, flash memory, battery backup SRAM, AsicKey & other I/O functions. Nearly all kinds of I/O functions can be implemented by this bus.
The integrated modular design of the expansion board allows a fast, easy, and flexible way of upgrading our controller's capability.
