KL2521-0010
by Beckhoff
The Beckhoff KL2521-0010 module, part of the KL Analog Input Modules series by Beckhoff, delivers a precise 1-channel pulse train output with a duty factor of 50% (±120%) and supports incremental encoder simulation via an RS422 output specification at 50 mA. With PWM clock frequencies up to 500 kHz (50 kHz default), this compact IP20-rated terminal is engineered for industrial automation applications requiring high-precision signal generation and reliable performance in control systems.
Incorporating a resolution of up to 15 bit and an output current of 0.5 A, the KL2521-0010 achieves fine-grained control over simulated encoder signals. The module’s typical K-bus current consumption of 50 mA (max. 120 mA, load-dependent) ensures efficient power management. Two 230 V AC/DC digital outputs extend flexibility for integrated switching functions. Electrical isolation of the K-bus and field-voltage outputs up to 500 V provides robust protection, while pluggable wiring simplifies installation and servicing. Conforming to EN 61000-6-2 and EN 61000-6-4, the terminal exhibits excellent immunity to electromagnetic disturbances and low emissions, ensuring stable operation in electrically noisy environments.
Designed for durability and versatility, the KL2521-0010 operates across a temperature range of 0…+55 °C and withstands storage conditions from –25…+85 °C. It meets EN 60068-2-6 vibration and EN 60068-2-27 shock resistance standards and tolerates up to 95% relative humidity (non-condensing). Weighing approximately 50 g with a compact IP20 housing and variable installation position, this bus terminal offers seamless compatibility with all KSxxxx series terminals. The rapid ramp calculation time of 2 ms per step and robust protection rating make it an ideal choice for high-speed, precision industrial processes, enhancing efficiency and reliability across automation networks.
