Macromatic TR-50222-07 Dpdt Time Delay Relay 10A 120V

Product Description

The MACROMATIC TR-50222-07 is a double-pole double-throw (DPDT) time delay relay designed for control circuit applications in commercial and industrial electrical systems. It features an 8-pin configuration and supports multiple timing ranges, selectable via a front-mounted knob. The relay is rated for 10 contact amps and operates on 120 VAC/VDC coil voltage. Licensed electricians and control system technicians install this type of relay to introduce a programmable time delay in switching circuits, enabling sequenced equipment startup, shutdown delay, or timed load control.

This relay is suited for use in a range of lighting control, motor control, HVAC sequencing, and industrial automation panels. The multiple-range knob adjustment allows a single unit to cover a broad span of delay intervals without swapping timing modules. It is appropriate for both new panel builds and retrofit applications where a field-adjustable, plug-in time delay relay is required. Installation environments include commercial buildings, light industrial facilities, and mechanical equipment rooms.

Key Features

• DPDT output contacts rated at 10 amps for versatile switching capability
• Operates on 120 VAC/VDC coil voltage for standard control circuit compatibility
• 8-pin plug-in base for quick installation and replacement in standard relay sockets
• Multiple timing ranges selectable via front-mounted knob - no tools required for range changes
• Compact form factor suited for DIN-rail panel or socket-mount installations

Compatibility

Designed as an OEM-style replacement or new-install plug-in time delay relay for standard 8-pin relay socket bases used in commercial and industrial control panel applications.

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 inserting or removing the relay from its socket base. Verify that the socket base pin configuration matches the 8-pin layout before applying power. Set the desired timing range and delay value using the front knob before commissioning the circuit.
