Macromatic TR-53122-15 Time Delay Relay Dpdt 120VAC

Product Description

The MACROMATIC TR-53122-15 is a DPDT time delay relay built for repeat-cycle timing applications in industrial and commercial control circuits. It operates on 120 volts AC/DC and delivers 10 amps of contact capacity through an 8-pin plug-in base. The timing range is adjustable via a front-panel knob, with a minimum delay of 18 seconds and a maximum delay of 30 minutes. Multiple timing ranges are selectable, giving technicians flexibility across a wide variety of sequencing and cycling tasks. This relay is a standard component in machine control panels, HVAC interlock circuits, and automated process systems.

The TR-53122-15 fits residential and commercial control applications where repeat-cycle timing is required. Typical use cases include fan delay sequencing, compressor short-cycle protection, pump alternation, and process equipment staging. The 8-pin octal footprint allows drop-in installation into standard relay sockets already common in many control panels. The knob-adjustable timing mechanism makes field setup straightforward without additional tools or programming hardware.

Key Features

• Repeat-cycle timer function for automatic on/off sequencing
• DPDT contact configuration rated at 10 amps
• 120 volt AC/DC coil voltage suits standard control circuits
• Multiple timing ranges with adjustable knob - minimum delay of 18 seconds, maximum of 30 minutes
• 8-pin octal base for plug-in installation into standard relay sockets

Compatibility

Designed as an OEM-style replacement or new-installation component for 8-pin octal relay sockets used in industrial and commercial control panels requiring 120 volt repeat-cycle timing.

Installation Notes

Installation should be performed by a licensed electrician or qualified control technician familiar with NEC requirements for control circuit devices. De-energize and lock out the control panel before inserting or removing the relay from its socket. Verify socket pin orientation matches the relay wiring diagram before applying power. Do not exceed the rated contact current of 10 amps to avoid contact damage or premature failure.
