KS4494
by Beckhoff
The Beckhoff KS4494 module is part of the KS Digital Input Modules series, designed by Beckhoff for high-precision industrial automation. This I/O terminal features electric isolation of 500 V between the K-bus and signal voltage and supports a signal voltage range of -10…+10 V. With a 12-bit resolution and dual channels for both inputs and outputs, it serves as a reliable bridge between field devices and higher-level control systems, ensuring accurate measurement and control of analog parameters.
In its technical design, the KS4494 offers a fast conversion time of < 2 ms, enabling near-instantaneous data updates for real-time process control. The input stage presents an internal resistance of > 130 kΩ, while outputs can drive loads of > 5 kΩ with short-circuit proof protection. Output accuracy is guaranteed by an error of < ±0.3% relative to the end value. The module draws power directly via the K-bus, simplifying installation and reducing wiring complexity. It complies with EN 60068-2-6 and EN 60068-2-27 standards for vibration and shock resistance, highlighting its suitability for demanding industrial environments.
Built for robust performance, the KS4494 operates reliably within an operating temperature range of 0…55°C and carries a protection rating of IP20 for flexible mounting options. Weighing approximately 55 g, the compact terminal integrates seamlessly into automation racks. The combination of high isolation voltage, precision resolution, rapid conversion, and conformity to shock and vibration standards makes this module an ideal choice for efficient, durable, and safe signal processing in modern industrial applications.
