Allen-Bradley module 1784-PCIC is an interface card used in industrial automation systems. It belongs to the Allen-Bradley Data Highway Plus series, which is a network protocol used to connect devices in a control system.

The 1784-PCIC module is designed to be installed in a personal computer (PC) and provides the PC with the capability to communicate on a Data Highway Plus network. It serves as an interface between the PC and the network, allowing the PC to exchange data with other devices connected to the Data Highway Plus network, such as Allen-Bradley programmable logic controllers (PLCs) and other network devices.

The 1784-PCIC module supports various communication protocols, including the Data Highway Plus protocol and the Remote I/O (RIO) protocol. It typically uses a PCMCIA (Personal Computer Memory Card International Association) interface to connect to the PC.

Overall, the 1784-PCIC module is used to enable PC-based communication and control in industrial automation appli
