Series 130 PWM signal generator for series AP and CP

Precision PWM Control for Proportional Valves

The Series 130 Electronic Control Device is a high-performance PWM controller specifically designed for directly operated proportional valves, offering precision control and flexibility across various industrial environments.

At its core, the Series 130 transforms standard input signals—either 0–10V or 4–20 mA—into a PWM (Pulse Width Modulated) output, ensuring a current at the solenoid that directly mirrors the input signal. This enables smooth, accurate operation of proportional valves with a maximum output current of 1 A.

A key feature of this controller is its closed-loop current control, which dynamically compensates for voltage fluctuations and solenoid heating, maintaining stable and reliable performance over time. The user can also finely tune both minimum (offset) and maximum (span) current values to meet specific system requirements.

For further customization, the adjustable ramp function (0–5 seconds) allows gradual current transitions, reducing mechanical stress and ensuring smooth valve operation.

Key Features:

• Closed-loop current regulation up to 1 A for stable performance
• Dual signal input compatibility: 0–10 V or 4–20 mA
• Adjustable up/down ramp time: 0 to 5 seconds
• User-defined min and max current output
• Output frequency: 120 Hz to 11.7 kHz (fixed per valve type)
• Short-circuit and polarity inversion protection
• Flexible mounting orientation and compact polycarbonate housing
• IP54 protection rating for dependable operation in industrial settings

Whether you're integrating a new control system or upgrading an existing one, the Series 130 offers the reliability, configurability, and performance needed for precise proportional valve control in a wide range of applications.
