The ABB CI873A is an AC 800M communication interface for external Ethernet devices. This module connects to networks using the EtherNet/IP protocol. The ABB CI873A also supports DeviceNet protocol for industrial automation. It operates as a master device on the communication network. The TP867 Baseplate has two RJ45 Ethernet connectors on the module. Only the CH1 connector that supports 100 Mbps is used for operation. The ABB CI873A contains CEX-Bus logic, a communication unit, and a DC/DC converter. The converter supplies required voltage from +24 V supply through the CEX-Bus. Its article number is 3BSE092695R1 for accurate ordering.
