Appendix D Remote I/O

Both PCI-1241 and PCI-1242 support a powerful remote IO function that
dramatically save wiring by transferring the DIO command to serial com-
munication. The PCLD-8241 is a remote IO module that can work with
PCI-1241, 1242 and 1261 without extra configuration. You simply con-
nect the PCLD-8241 and PCI-1241/42 with a 9-pin cable, and they can
operate remote IO points with motion commands.

D.1 Features

The remote IO module PCLD-8241 has the following features

• Serial communication interface
•  64 digital inputs
•  64 PhotoMos-Relay outputs
• Full photo isolation
•  Din rail package
