Product Description:

The Beckhoff KS4494 is a I/O terminal for signal processing in industrial automation systems. It acts as a bridge between field devices and higher-level control systems, allowing seamless data communication and signal conversion. This terminal supports a wide variety of signal types and is built to handle the demands of analog input/output systems. It comes with 2-channel analog input and 2-channel analog output, providing versatile signal handling capabilities. The analog input channels enable the system to receive continuous measurements, such as temperature, pressure or flow, from various sensors. The analog output channels allow the terminal to transmit precise control signals to devices like actuators or controllers. This facilitates seamless bi-directional data flow for accurate system performance.

This terminal supports an input and output range of ±10 V, allowing it to handle a wide spectrum of analog signals. This voltage range ensures that the terminal can integrate smoothly into systems requiring precise analog control, offering accurate data processing and reliable performance even in complex automation setups. The terminal offers 12-bit resolution for both its analog input and output channels. This high resolution enables the terminal to capture and process signals with high precision, ensuring accurate measurement and control of analog parameters. This level of precision allows the system to respond to even the smallest fluctuations in signal, enhancing the reliability of the automation system.

The KS4494 uses single-ended technology for its analog input and output channels, allowing for a cost-effective and efficient design. It can support a 5 kΩ load and is short-circuit proof, ensuring safe operation. The terminal boasts a conversion time of less than 2 ms, enabling rapid signal processing and real-time data updates. This allows the system to respond to changes almost instantaneously, optimizing system responsiveness.
