Beckhoff KL2521 original digital output

The KL2521-0024 is a single-channel PWM (Pulse Width Modulation) output terminal from the Beckhoff Bus Terminal series (KL series) for the traditional K-Bus I/O system, with the -0024 suffix indicating a 24 V DC output variant. It generates a pulse-width modulated 24 V DC output signal for controlling proportional valves, heating elements, lamps, DC motors, and other devices that respond to a duty-cycle signal. Unlike EtherCAT terminals (EL series), the KL series communicates via the K-Bus and is typically used with Beckhoff Bus Couplers or Bus Terminal Controllers.
