Parker PRTF10 Pneumatic Time Delay Relay Off Delay

Product Description

The PARKER PRTF10 is a pneumatic time delay relay designed for off-delay timing applications in industrial and commercial control systems. It operates on a pneumatic timing mechanism, providing a timing range of 0.1 to 3.0 seconds with a normally open (NO) contact configuration. The subbase mount design allows for straightforward panel integration without direct wiring to the relay body, simplifying replacement and maintenance. Electricians and controls technicians working on relay-logic panels, motor control centers, and automated equipment will find this relay suited to timed shutoff and sequencing applications.

The PRTF10 is used in relay-based control circuits where a brief, adjustable off-delay is required before a downstream circuit opens. Typical applications include conveyor sequencing, motor control, pneumatic actuator timing, and industrial process automation. The subbase mount configuration is common in panel builds where relay sockets are pre-wired and individual relays must be swapped without disturbing field wiring.

Key Features

• Pneumatic timing mechanism with an adjustable range of 0.1 to 3.0 seconds
• Off-delay timing function for timed circuit release after signal removal
• Normally open (NO) contact form
• 2-pin configuration for subbase mount installation
• Subbase mount design simplifies relay replacement without disturbing field wiring

Compatibility

Designed as an OEM-style replacement for pneumatic time delay relays using a 2-pin subbase mount in industrial relay control panels and automation systems.

Installation Notes

Installation is performed by licensed electricians or qualified controls technicians. De-energize the control panel and verify zero voltage at the subbase socket before seating or removing the relay. Subbase mount relays are keyed to prevent misorientation, but confirm the socket type matches the PRTF10 2-pin footprint before installation. All work should comply with applicable NEC requirements for industrial control wiring.
