Supco td69 Time Delay on Make Timer 19-250V 1A

Product Description

The SUPCO td69 is a time delay on make (DOM) timer used in HVAC and refrigeration control circuits to introduce a controlled delay before a load is energized. Operating across a wide input voltage range of 19 to 250 VAC/VDC, this timer suits both low-voltage control applications and line-voltage circuits. It handles a maximum load of 1 amp continuous with an inrush tolerance of 10 amps, and requires a minimum load current of 40 milliamps at 24 VAC. The non-positional, single-hole mounting design simplifies installation in a variety of enclosures and control panels. Licensed HVAC technicians and refrigeration service professionals are the primary installers.

The td69 is suited for residential and light commercial HVAC systems, refrigeration equipment, and other electromechanical control applications where a delay on make function is required. Common uses include compressor short-cycle protection, fan delay sequencing, and staged equipment start-up in split systems, packaged units, and refrigeration cases. Its broad voltage compatibility makes it adaptable across many control board and relay panel configurations without requiring a dedicated transformer tap.

Key Features

• Wide input voltage range: 19 to 250 VAC/VDC covers both 24-volt control circuits and line-voltage applications
• 10-amp inrush tolerance supports motor and relay load starts
• Non-positional mounting allows any orientation in the enclosure
• Single-hole mounting simplifies panel installation
• 1/4 inch quick connect terminals for fast, tool-free wiring connections
• Operating temperature range of 0 to 160 degrees F suits most mechanical room and equipment cabinet environments

Compatibility

Designed as an OEM-style replacement time delay on make timer for residential and light commercial HVAC, refrigeration, and electromechanical control applications requiring a DOM function across a broad voltage range.

Installation Notes

Installation should be performed by a qualified HVAC technician or electrician. Disconnect and lock out all power to the unit before removing the existing timer or making wiring connections. The 1/4 inch quick connect terminals should be fully seated to ensure reliable contact. Follow all applicable NEC requirements and equipment manufacturer wiring diagrams when integrating this timer into a control circuit.
