Macromatic TR-53122-10 Time Delay Relay 10A 120VAC Dpdt

Product Description

The MACROMATIC TR-53122-10 is a dual-pole dual-throw (DPDT) time delay relay rated for 10 contact amps at 120 volts AC/DC. Built on an 8-pin base with a knob-style timing adjustment, it supports multiple timing ranges in a single unit, making it a versatile choice for industrial and commercial control circuits. Licensed electricians and control panel builders install this relay when an application requires adjustable on-delay or off-delay sequencing without swapping out hardware for different time ranges. The knob adjustment allows field calibration directly at the relay socket without additional tooling.

This relay is suited for residential, commercial, and light industrial electrical control panels where timed switching of loads is required. Typical applications include HVAC sequencing, lighting control, motor start delay, and process automation circuits. The 8-pin octal-style footprint fits standard relay sockets common in control panel construction. Its multiple-range capability makes it practical for contractors who need one part to cover a range of job-site timing requirements rather than stocking several single-range relays.

Key Features

• DPDT output contacts rated at 10 amps for reliable load switching
• 120 VAC/VDC coil voltage covers common North American control circuit standards
• Multiple timing ranges on a single unit reduce inventory and field changeover time
• Knob-style adjustment allows on-site timing calibration without special tools
• 8-pin base is compatible with standard octal relay sockets

Compatibility

Designed as an OEM-style replacement or direct-install time delay relay for 8-pin octal relay socket applications in residential, commercial, and light industrial control panels requiring 120 VAC/VDC coil voltage and DPDT switching.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize the control panel and verify absence of voltage before inserting or removing the relay from its socket. Seat the relay firmly into the 8-pin socket and confirm proper pin alignment before restoring power. Set the timing knob to the desired range and adjust to the target delay interval during commissioning.
