WIKA Model PSD-4-ECO OEM pressure switch with display
$120.00
The WIKA PSD-4-ECO is an OEM-designed electronic pressure switch with an integrated digital display that visually indicates pressure status and provides switch outputs for control or alarm tasks. Its compact size and configurable display make it ideal for machine builders and automation applications requiring quick integration and visual feedback.
Typical Applications:
• Hydraulics and pneumatics OEM machines
• Automation and special purpose machine building
• Machine tools and embedded pressure control
• Process pressure monitoring with discrete switching
• Pneumatic systems requiring pressure feedback
Not Recommended For:
• Continuous analog pressure measurement without switching logic
• Applications demanding fieldbus / high-bandwidth control (use higher-end IO-Link instruments instead)
Selection Notes
• Confirm pressure range and switching logic needed for your system
• Determine whether color display feedback (green/red) will assist operators
• Check compatibility with your controller (PNP/NPN or IO-Link 1.1)
• Evaluate environmental conditions – rated for shock up to 50 g and wide temperature range (-40 … +125 °C)
Why Choose WIKA PSD-4-ECO Pressure Switch with Display
• Visual Good/Bad Status: Parameterisable display lights green when pressure is within set range, red when out of range for fast diagnostics.
• Compact OEM Integration: Slim diameter and rotatable display head make it easy to integrate in tight spaces inside machinery.
• Programmable & IO-Link Ready: Offers flexible setup or factory pre-configuration, saving engineering time and reducing commissioning effort.
• Robust Design: Designed for tough environments with shock resistance up to 50 g and wide temperature operating range.
• Switch Outputs: Enables direct control, alarm triggering, or interlocking functions based on pressure trends.
FAQ
Q: What display feedback does PSD-4-ECO provide?
A: The pressure switch display can be configured to show green when pressure is within the set window and red when outside it, enabling fast visual checks.
Q: Can this pressure switch be integrated into automation systems?
A: Yes — it supports switching outputs and IO-Link 1.1 communication for integration with automation controllers.
Q: Is the PSD-4-ECO suitable for harsh industrial environments?
A: Yes — it’s designed for tough conditions, with shock resistance up to 50 g and temperature ratings from -40 °C to +125 °C.
Q: Does it come factory pre-configured?
A: It can be pre-parameterised by WIKA or set up via IO-Link, reducing installation time.
