1785-KA
Allen Bradley Interface Module

The 1785-KA is a Data High Plus Interface Module. The 1785-KA Provides an interface  between Data Highway Plus and Data Highway-485 link. The Data Highway Plus (DH+) network is a local area network designed to support remote programming and data acquisition for factory-floor applications. You can also use DH+ communication modules to implement a small peer-to-peer network.

You can use a DH+ network for data transfer to other PLC-5 controllers or high-level computers and as a link for programming multiple PLC-5 controllers. A PLC-5 controller can communicate over a DH+ network with other controllers and with a workstation. The DH+ network supports daisy-chain and trunkline-dropline configurations.
