Hartland Controls tp-90370 24 Vac Spdt General Purpose Relay

Product Description

The HARTLAND CONTROLS tp-90370 is a general purpose switching relay rated for 24 VAC operation with SPDT switching capability. It is designed for control circuit applications in HVAC, refrigeration, and light commercial equipment where reliable low-voltage switching is required. The relay features a Class B insulation system and a double make contact configuration, providing both normally open and normally closed switching options in a single unit. Licensed HVAC technicians and controls specialists are the primary installers of this relay in field wiring and OEM panel assemblies.

This relay is suited for residential and light commercial HVAC control boards, fan relay panels, and general purpose switching enclosures. Its multi-positional mounting design allows flexible installation in a variety of panel orientations. The 0.250-inch quick-connect terminals simplify field wiring connections. Where space or panel layout is a constraint, the compact form factor and mounting flexibility make it a practical choice for retrofit and new-construction control panel work alike.

Key Features

• 24 VAC coil voltage for standard low-voltage control circuit compatibility
• SPDT switching with 1 NO and 1 NC contact configuration
• Double make contact design for reliable circuit switching
• Class B insulation system for thermal durability in control environments
• 0.250-inch quick-connect (QC) terminals for fast field termination
• Multi-positional mounting for flexible panel installation
• UL 508 listed (File No. E227250, Class NLDX2 and DNLDX8)

Compatibility

Designed as an OEM-style general purpose switching relay for use in HVAC control panels, relay boards, and light commercial control enclosures requiring 24 VAC SPDT relay functions.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified controls electrician. De-energize and lock out the control panel before removing or installing the relay. Verify that the supply voltage matches the 24 VAC coil rating before energizing. Wiring should comply with NEC low-voltage control circuit requirements and any applicable local codes.
