The Allen-Bradley 1774-KA communication adapter is used to link smart RS-232-C or RS-422-A devices to the Allen-Bradley communication network. The unit has been designed as a local area network communication module, and it is used mostly for plant floor applications. The data highway features industrial-hardened surfaces, and a floating master communication function, allowing for reliable data transport. The communication adapter features the Allen-Bradley PLC-2 programmable controller. This PLC-2 programmable controller can communicate over the data highway. However, this requires a slot for it to be included in the 1771 I/O Chassis. This capability enables the users to achieve a plant-wide computer integrated manufacturing process.

The 1774-KA features structured cabling that provides the physical capability to transport data between different nodes. The 1774-KA cabling features various parts including a trunkline, droplines, and station connectors. It comes with various interface ports, including ports for the PLC-2 programmable controller, the Data Highway dropline, and the Allen-Bradley industrial terminal. The 1774-KA communication adapter features the full-duplex and the half-duplex protocols on the asynchronous link. The module should be placed in and used in an environment where the conditions are always favorable to ensure longevity. The ambient operating temperature should be rated between 0 and 45 degrees Celsius while the humidity rating should be between 10% and 80%, non-condensing.
