Macromatic TR-50222-22 Dpdt Time Delay Relay 10A 120V

Product Description

The MACROMATIC TR-50222-22 is a DPDT (double-pole, double-throw) time delay relay designed for control circuit applications in industrial, commercial, and HVAC electrical systems. It operates on 120 volts AC or DC and provides a multiple-range delay function with a maximum delay of 10 minutes, adjustable via a knob-style control. The relay is rated at 10 amps contact current and fits standard 8-pin octal sockets. Electricians and controls technicians use this relay to introduce timed sequencing into motor control panels, HVAC staging circuits, and general-purpose switching applications.

This relay is suited for residential and commercial control panel installations where timed on-delay or off-delay switching is required. It is commonly wired into low-voltage control circuits to manage compressor sequencing, fan staging, lighting control, or other time-critical load switching. The 8-pin footprint accommodates standard octal relay sockets, making installation and field replacement straightforward without rewiring the base.

Key Features

• DPDT contact configuration provides two independent switched circuits per relay
• Multiple delay range selection with knob adjustment up to 10 minutes
• 120 VAC or VDC coil voltage suits common control circuit applications
• 10 amp contact rating handles typical control and light-load switching
• 8-pin octal form factor is compatible with standard relay sockets

Compatibility

Designed as an OEM-style replacement for 8-pin octal DPDT time delay relays in industrial and commercial control panel applications rated at 120 VAC or VDC.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize and lock out the control panel before removing or inserting the relay into its socket. Verify coil voltage and contact ratings match the circuit requirements before energizing. Do not exceed the 10 amp contact rating for the switched load.
