Parker PRTD10 Pneumatic Time Delay Relay Off Delay

Product Description

The PARKER PRTD10 is a pneumatic time delay relay designed for off-delay timing applications in industrial and commercial control systems. It provides a selectable timing range of 10 to 180 seconds, allowing technicians to dial in the exact delay interval required by the application. The relay uses a subbase mount configuration and features a normally open (NO) contact form with a 2-pin configuration. Licensed electricians and industrial control technicians are the primary installers of this relay type. It is well suited for sequencing, motor control, and process automation panels where a reliable, pneumatically timed off-delay function is required.

The PRTD10 fits into control panel builds and automation systems that require a self-contained, pneumatic timing mechanism without reliance on electronic circuitry. Its subbase mount design allows the relay body to be swapped without disturbing field wiring, which simplifies maintenance and reduces panel downtime. Typical installations include HVAC control panels, industrial machinery interlocks, and conveyor or pump sequencing applications where an off-delay function is needed to extend equipment run time after a control signal is removed.

Key Features

• Off-delay timing function with a selectable range of 10 to 180 seconds
• Pneumatic timing mechanism — no electronic timing circuit required
• Subbase mount design allows relay body replacement without rewiring
• Normally open (NO) contact form for standard interlock and sequencing applications
• 2-pin contact configuration for straightforward panel wiring

Compatibility

Designed as an OEM-style replacement or new-installation pneumatic time delay relay for subbase-mount control panel applications requiring off-delay timing.

Installation Notes

Installation should be performed by a licensed electrician or qualified control panel technician in accordance with applicable NEC requirements. De-energize and lock out the control panel before removing or installing the relay. The subbase must be securely mounted and wired before seating the relay body. Verify the timing adjustment and contact form match the application requirements before restoring power.
