SDC0FF0I
Industrial I/O Control PCIe Card
16+16-ch Isolated Digital I/O
- Designed to meet PCI Express Base Specification Revision 2.1.
- With high reliable SUNIX QiuNiu UART Digital-I/O controller.
- Plug-n-Play, I/O address and IRQ assigned by system.
- Ultra low power consumption (<1.5W) design for green environment and industrial application.
- High quality electronic components, low impedance and high stability ensure product quality and reliability.
- Support Microsoft Windows 10/11 with C and C# programming language sample code.
- Providing a customizable API platform to meet IoT application needs.
- Certified by CE, FCC, RoHS, and Microsoft approvals.
- Support both standard and Low profile bracket design to meet various PC chassis.
Digital I/O Communication:
-
Expands isolated eight (16) digital input channels with features for all channels.
- Support both NPN & PNP devices
- Support both dry and wet contact connections
- With digital filter for noise reduction
- Built-in 32-bit counter for all digital in channels
- Expands isolated eight (16) NPN type digital output channels with initial value (Booting & Restart) protection.
- Each channel built-in 2.5KV isolation protection for signal and power, allowing the input signals to be completely floated so as to prevent ground loops.
