The 1775-KA is tailored for efficient interfacing within the PLC 3 series. This device supports data transfers effectively, catering to both RS-232-C and Data Highway communication protocols. Users have the option of connecting it to either 115 V AC or 230 V AC power lines, making it a versatile choice for a variety of electrical environments.
High-Speed Data Highway
3.75A Backplane Power
Dual-Link Versatility
The module is designed to operate at a frequency of 50/60 Hz, making it suitable for use in different regional electrical systems. Power consumption remains low, at just 3.5 Watts, ensuring it does not impose significant load on the overall system. It is equipped with status indicators that communicate both communication and functional statuses for ease of monitoring. Furthermore, it features a built-in diagnostic utility that performs a pass/fail self-test, allowing users to quickly ascertain operational readiness.

Automotive Manufacturing
The module provides a high-speed data link between multiple processors for coordinated assembly line control. It facilitates the transfer of production data and inter-processor interlocking required for robotic welding and painting.
Steel Processing
Utilized in heavy industrial environments to manage data exchange across long distances up to 10,000 feet. It supports the rugged communication needs for blast furnace monitoring and rolling mill synchronization via twinaxial cable.
Petrochemical Refineries
Interfaces with remote I/O links to collect sensor data from distributed processing units and storage tanks. The architecture allows centralized monitoring of pressure, temperature, and flow rate parameters across the facility.
Food & Beverage
Manages peer-to-peer communication for high-volume batching, mixing, and packaging systems. It ensures real-time updates of recipe parameters and inventory levels between the main controller and specialized processing stations.
Material Handling
Integrates complex conveyor systems and automated storage and retrieval systems within large distribution centers. The module handles the frequent data updates necessary for tracking carrier locations and sorting logic on the link.
Pulp & Paper
Supports the continuous process control requirements of paper machine drives and wet-end chemical processing. It provides a stable communication interface for coordinating speed and tension control across multiple drive sections.
The 1775-KA module requires specific installation and maintenance procedures to ensure long-term reliability within a PLC-3 system architecture. It must be securely seated in the local or remote chassis, drawing 3.75 Amperes from the 5V DC backplane, and should only be inserted or removed when chassis power is disconnected to prevent backplane damage.
The module incorporates a 1770-CD shielded twinaxial cable interface for Data Highway and Remote I/O links, which necessitates the installation of 150-ohm terminating resistors at each end of a physical trunk line to suppress signal reflections. Configuration is handled through hardware DIP switches on the circuit board, where users must manually set the unique station octal address and select between 57.6 Kilobaud or 230.4 Kilobaud communication rates.
For troubleshooting, the front-panel DIAG indicator serves as a critical diagnostic tool, remaining lit during the power-up self-test and extinguishing only upon a successful "pass" status, while a flashing or steady light during operation signals an internal hardware or parity error.
What is the primary function of the 1775-KA Communication Interface Module?
The 1775-KA module provides an interface between the PLC-3 processor and the Data Highway or a Remote I/O link, enabling the processor to communicate with other controllers or remote I/O chassis.
What is the backplane current draw for a 1775-KA module at 5V DC?
The 1775-KA module draws 3.75 Amperes of current from the 5V DC backplane power supply.
Which communication rates are supported by the 1775-KA for Data Highway links?
The 1775-KA supports Data Highway communication at 57.6 Kilobaud or 230.4 Kilobaud, depending on the switch settings on the module.
How are the station addresses configured for the 1775-KA module?
Station addresses are set using the 8-position DIP switches located on the module’s printed circuit board to define its identity on the link.
What do the DIAG and ACTIVE status indicators on the 1775-KA front panel represent?
The ACTIVE indicator lights when the module is communicating on the link, while the DIAG indicator signals the result of internal self-tests or hardware faults.
