KL2124
The Beckhoff KL2124 module is a high-performance addition to the KL Analog Input Modules series designed for industrial automation applications. This compact Bus Terminal features 4 outputs and operates at a nominal voltage of 5 V DC, supporting precise analog signal acquisition. With an approximate weight of 70 g and built-in reverse voltage protection, the KL2124 provides reliable performance in demanding environments. Its primary function is to convert field signals into digital data for safe transmission over the K-bus, facilitating seamless integration with Beckhoff control systems.
Detailed technical specifications of the KL2124 underscore its versatility and robustness. The module employs a 2-/3-wire connection technology and delivers a signal current of 8 mA per channel for stable operation with ohmic, inductive, and lamp loads. Each channel is short-circuit proof with a maximum output current of ±20 mA, ensuring system safety under fault conditions. The device’s current consumption on the power contacts is 16 mA (typ.) + load, while the K-bus itself requires 14 mA. It meets stringent EMC requirements under EN 61000-6-2 and EN 61000-6-4, guaranteeing immunity to industrial interference.
Additional features of the KL2124 include an isolation voltage of 500 V between the internal bus and field potentials, enhancing operator safety and signal integrity. The module operates reliably within an ambient temperature range of 0 to 55 °C and affords protection against dust and solid contact to IP20 standards. It withstands vibration and shock per EN 60068-2-6 and EN 60068-2-27 respectively, and does not require manual addressing thanks to its seamless plug-in design. In industrial applications, the Beckhoff KL2124 offers exceptional durability, precise analog input handling, and efficient signal processing, boosting system availability and simplifying installation.
