Beckhoff KS4002 Bus Terminal Analog Output Voltage

Beckhoff KS4002 is a two-channel analog output terminal for the K-Bus that delivers 0–10 V DC control signals to analog actuators and process devices. Each channel provides a 0–10 V output with 12‑bit resolution (4096 steps) and the two outputs share a common ground reference, simplifying wiring in multi-channel applications. The module is powered via the K-Bus, with a recommended load per channel greater than 5 kΩ and an output error of less than ±0.1% of the end value, ensuring tight accuracy in automation tasks. Conversion time is approximately 1.5 ms, enabling timely updates in PLC control loops. Typical uses include driving valves, analog actuators, or other 0–10 V compatible instrumentation controlled by Beckhoff PLCs, with straightforward integration through standard K-Bus wiring and a Beckhoff controller.
