Smart Electric SAM8 Delay on Make Relay

Product Description

The SMART ELECTRIC SAM8 is a delay on make relay designed for use in HVAC control circuits where a timed startup delay is required before a load is energized. This type of timing relay introduces a preset off-to-on delay, allowing downstream equipment to sequence properly rather than starting simultaneously. It is a single-unit component installed by licensed HVAC technicians in residential and light commercial systems to protect compressors, motors, and other load devices from simultaneous startup conditions.

The SAM8 is suited for applications where compressor short-cycle protection or load sequencing is required. Delay on make relays are commonly installed in split-system air conditioners, heat pumps, and refrigeration equipment. The single-unit form factor makes it straightforward to integrate into existing control panels or equipment wiring compartments.

Key Features

• Delay on make timing function holds load off until the delay period elapses after power is applied
• Supports compressor short-cycle protection and staged equipment startup
• Single-unit design for direct installation into control circuits
• Compact form factor suitable for residential and light commercial HVAC applications

Compatibility

Designed as an OEM-style replacement or aftermarket addition for HVAC control circuits requiring a delay on make timing relay function.

Installation Notes

Installation should be performed by a qualified HVAC technician in accordance with applicable electrical codes, including the NEC. Disconnect and lock out all power to the unit before servicing control wiring. Verify control circuit voltage requirements match the relay specifications before wiring. Do not energize the relay until all wiring connections are secure and inspected.
