Advantech ISA bus data acquisition and control card | digital input and output PCL-722 | 144 / No Power Products PCL-722 is a 144-channel digital input / output full-length card, which provides a 144-channel parallel digital input / output from six 50-pin pin-channel interface. Each channel interface emulation programmable parallel I / O interface chip mode 0 8255, has 24 digital input / output interface. Pin definition and Opto-22 modules are fully compatible. The first port of C 0 and the third can generate an interrupt IRQ2 ~ 7. Product Features 1.144 TTL digital I / O ports (6 ports, each with 24 channels I / O port) 2. Each connection port 24-channel I / O ports can be set to the PA port (8 bit), PB port (8), PC port and the PC port high four low 4, each I / O port can be set to input or output software provides higher drive capability than 8255 3. buffer circuit can be directly connected to a wide range of peripheral devices. 4.
