Rexroth HED8OH-20 50K14 Pressure Relay with 24V DC Power and ±0.5% Accuracy for Industrial Control Systems

The Rexroth HED8OH-20 50K14 Pressure Relays deliver high-precision control and electrical safety for demanding industrial applications, featuring ±0.5% accuracy with advanced PID closed-loop regulation technology.

• High-precision control: ±0.5% accuracy with PID closed-loop regulation technology
• Pressure protection: Damping hole structure buffers sudden pressure changes
• Durable construction: Oil-resistant rubber sealing rings and precision-machined valve body
• Intelligent diagnostics: LED status indicators and fault code output
• Wide compatibility: 24V DC input compatible with industrial standard power supplies
• Versatile applications: Suitable for machine tools, injection molding machines, and metallurgical equipment

Selection and Installation: Choose appropriate model for system pressure range (HED 8 series supports 250Bar). Ensure terminal tightening and protection from electromagnetic interference. Use shielded cables for signal lines to reduce noise.

Maintenance Requirements: Calibrate set values using Rexroth special software. Regularly check spring preload and micro switch contacts. Perform functional tests every 2000 hours of operation.

Environmental Considerations: Avoid high dust concentration or humidity >90% environments. Do not use with unclean hydraulic oil or impurity-containing media. For long-term storage, apply anti-rust oil and seal package.
