Product Description

The KL2521-0010 Bus Terminal from Beckhoff is made for industrial automation systems that need precise pulse train output. The terminal is part of Beckhoff's KL Analog Input Series and is designed to work reliably and meet high-performance standards. Because the interface is small and flexible, it can be used in a number of different control systems.

The KL2521-0010 bus terminal gives off a single-channel pulse train with an RS422 signal type for simulating an incremental encoder. The terminal has a duty factor of 50% (±20%) and a precision of up to 15 bits. The power that comes out is 0.5 A, and the PWM clock frequency can be 1 to 500 kHz. The terminal is set to 50 kHz by default and has two 230 V AC/DC digital outputs. The K-bus terminal usually uses 50 mA of current but can use up to 120 mA based on the load. The K-bus and field voltage outputs are electrically isolated up to 500 V. The terminal meets the EMC standards EN 61000-6-2 and EN 61000-6-4, that means it has strong electromagnetic protection and emission performance.

The KL2521-0010 Bus Terminal’s temperature range for the end is 0°C to +55°C, and the temperature range for storage is -25°C to +85°C. The terminal is made to be waterproof up to IP20 standards and can be installed in a number of different ways. According to EN 60068-2-6 and EN 60068-2-27, the terminal can handle shaking and shock. Besides weighing about 50 g, the KL2521-0010 has a ramp calculation time of 2 ms per step and can work in environments with up to 95% relative humidity without condensation. We offer global shipping and a guarantee that covers replacements for one year.
