Hartland Controls tp-90293 Relay 24 Vac Spdt

Product Description

The HARTLAND CONTROLS tp-90293 is a general purpose switching relay rated at 24 volts AC with SPDT switching configuration. It is designed for low-voltage control circuit applications found in HVAC systems, including heating and cooling equipment where reliable switching of control signals is required. The relay features Class B insulation and a double make contact design, providing both normally open and normally closed switching paths. Licensed HVAC technicians and controls installers are the primary professionals who specify and install this relay in field wiring and panel assemblies.

This relay is suited for residential and light commercial HVAC control applications where general purpose switching at 24 VAC is needed. It supports SPNO, SPDT, 1 NO, and 1 NC switching configurations, making it adaptable to a range of control wiring scenarios. The multi-positional mounting design allows flexible installation inside control panels, junction boxes, or directly on equipment frames depending on the application requirements.

Key Features

• 24 VAC coil voltage for standard low-voltage HVAC control circuit compatibility
• SPDT switching with both normally open and normally closed contacts
• Double make contact configuration for reliable circuit switching
• Class B insulation system for thermal durability in control applications
• 0.250 inch quick-connect terminals for straightforward field wiring
• Multi-positional mounting for flexible panel or equipment installation
• UL 508 listed under File No. E227250, Class NLDX2 and DNLDX8

Compatibility

Designed as an OEM-style general purpose relay replacement for 24 VAC low-voltage control circuits in residential and commercial HVAC systems.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified controls electrician. De-energize and lock out the control circuit before removing or installing the relay to prevent accidental activation. Quick-connect terminals accept standard 0.250 inch push-on connectors; confirm terminal fit before applying force. Wiring should comply with NEC requirements for low-voltage control circuits and any applicable local codes.
