It features two independent, current-controlled PWM output channels for direct connection to inductive loads such as proportional valves or electromagnetic actuators. Each output channel is protected against overloads and short-circuits, ensuring reliable field operation. The terminal is galvanically isolated from the K-bus, offering enhanced system protection, and its LED indicators simplify fault diagnosis during operation or maintenance. Key Features: Dual PWM Channels: Provides two independently controlled PWM outputs for flexible load management. Precise Current Regulation: Maintains accurate current control from 0 to ±1 A through 16-bit signal input. High-Frequency Operation: Operates at a 36 kHz PWM clock frequency for smooth and efficient current modulation. Galvanic Isolation: Electrically isolated 500 V between K-bus and field potential enhances operational safety. Integrated Protection: Output stage is safeguarded against overloads and short-circuits for dependable use. Status Indication: Built-in LEDs display load and wiring states for quick local diagnostics. Flexible Configuration: Supports configuration via Bus Coupler or controller without manual address setting. Industrial Durability: Designed for long-term stability in environments with temperatures from -25°C to +85°C. The KL2535 delivers the reliability and precision required for industrial control systems involving proportional loads, coils, and other current-driven devices.
