PIO-D24 24-channel Digital IO Board

• Description
• Features
• Specifications
• Technical

The PIO-D24 provides 24 TTL digital I/O lines, consisting of three 8-bit bi-direction ports. The 8-bit ports are named port A (PA), port B (PB), port C (PC) with all ports being configured as inputs upon power-up or reset.

The PIO-D24 has one D-Sub connector

This card can be installed in a 32-bit 5 V PCI bus and can support "Plug & Play".

NOW Universal PCI so can be installed in 3.3V or 5V bus PCI slots. 

• 32-bit +5V PC compatible PCI bus, Plug and Play
