Introduction
Compared
to I-7188EX, the I-7188EA adds seven open-collector output channels
and six digital Input channels. I/O Expansion bus has been occupied
by DI/O expansion board. Therefore I-7188EA is used as an Embedded
Internet / Ethernet Controller with several built-in D I/O channels.
If the user want to know more detail of I-7188EX, refer to I-7188EX
for further information.
