Parker PRTC10 Pneumatic Time Delay Relay Subbase Mount

Product Description

The PARKER PRTC10 is a pneumatic time delay relay designed for off-delay timing applications in industrial and commercial control systems. It operates on an air-actuated timing mechanism, providing a timing range of 0.1 to 30 seconds with a normally open (NO) contact form. The subbase mount configuration allows for clean panel integration and straightforward wiring access. This relay is installed by licensed electricians and HVAC controls technicians working on automated sequencing, fan shutdown delays, and process control circuits where a timed output shutoff is required after the input signal is removed.

The PRTC10 fits control panel and equipment applications where pneumatic timing logic is preferred over electronic timers, particularly in environments where electromagnetic interference is a concern. Its two-pin contact configuration keeps wiring simple, making it a practical choice for retrofit and new-installation control panels in light industrial, commercial HVAC, and building automation contexts. The subbase mount style is standard in many relay panel assemblies, allowing the relay body to be swapped without disturbing field wiring.

Key Features

• Off-delay timing function holds the output closed for a set period after the input signal is removed
• Timing range of 0.1 to 30 seconds covers a wide range of sequencing applications
• Pneumatic timing mechanism provides reliable operation in electrically noisy environments
• Normally open (NO) contact form for standard control circuit integration
• Subbase mount design allows relay body replacement without rewiring
• Two-pin contact configuration simplifies installation and troubleshooting

Compatibility

Designed as an OEM-style replacement or upgrade for subbase-mount pneumatic time delay relay sockets in commercial and industrial control panel assemblies.

Installation Notes

Installation should be performed by a qualified electrician or licensed controls technician in accordance with NEC requirements. De-energize and lock out the control panel before removing or installing the relay. Verify that the subbase socket is compatible with the two-pin configuration before seating the relay body. Adjust the timing dial to the required delay interval and confirm operation with a test cycle before returning the system to service.
