The CI873A 3BSE092695R1 is an AC 800M communication interface that connects to external Ethernet devices using the EtherNet/IP protocol. The TP867 Baseplate has two RJ45 Ethernet connectors, but only the CH1 connector that supports 100Mbps is used. The CI873 expansion unit contains the CEX-Bus logic, a communication unit, and a DC/DC converter that supplies the required voltage from +24V supply through the CEX-Bus.
Basic Information
Product Model: CI873A
Product Number: 3BSE092695R1
