Hartland Controls tp-90380 Relay 24 Vac 1 No 1 Nc

Product Description

The HARTLAND CONTROLS tp-90380 is a general purpose switching relay rated for 24 VAC operation, offering both SPNO and SPDT switching configurations with 1 NO and 1 NC contact arrangement. Designed for control circuit applications, this relay features a Class B insulation system and a double make contact configuration. The .250 inch quick-connect terminals allow for straightforward wiring, and the multi-positional mounting design gives installers flexibility when fitting the relay into control enclosures or equipment cabinets. Licensed electricians and HVAC controls technicians are the primary trades that install and commission this component.

This relay is suited for residential and light commercial control applications where reliable general purpose switching is required. Typical installations include HVAC control panels, zone control boards, and low-voltage switching circuits operating at 24 VAC. The SPDT configuration supports both normally open and normally closed control logic, making it adaptable to a range of switching scenarios encountered in field service and panel assembly work.

Key Features

• 24 VAC coil voltage for compatibility with standard low-voltage control circuits
• SPNO and SPDT switching configurations with 1 NO and 1 NC contacts
• Double make contact configuration for enhanced circuit reliability
• Class B insulation system for thermal durability in control environments
• .250 inch QC terminals for fast, tool-free wiring connections
• Multi-positional mounting for flexible installation in enclosures and panels
• UL 508 listed, File No. E227250, Class NLDX2 and DNLDX8

Compatibility

Designed as an OEM-style general purpose switching relay for 24 VAC low-voltage control circuit applications in residential and light commercial HVAC and electrical systems.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC controls technician in accordance with NEC requirements. De-energize the control circuit and verify the absence of voltage before removing or installing the relay. Confirm that the coil voltage and contact configuration match the control panel design before wiring. Secure the relay firmly using the multi-positional mounting feature to prevent vibration-related contact issues during operation.
