Honeywell SZR-LY2-N1 110VAC General Purpose Relay – SZR Series DPDT 8-Pin
When a relay fails mid-production, the consequences cascade instantly — conveyor lines halt, safety interlocks trip, and unplanned downtime costs mount by the minute. In industrial control panels, PLCs, and machine automation circuits, the general purpose relay is the silent backbone of every switching operation. Without a reliable, spec-matched relay like the Honeywell SZR-LY2-N1 110VAC, even the most sophisticated control system becomes vulnerable to nuisance trips, contact welding, and catastrophic process interruption.
The SZR-LY2-N1 occupies a well-established position within Honeywell’s SZR Series — a line engineered for demanding industrial environments where switching reliability, compact footprint, and broad coil voltage availability are non-negotiable. With a 110VAC coil voltage, DPDT (Double Pole Double Throw) contact configuration, and standard 8-pin octal base, this relay integrates seamlessly into global control architectures from North America to Asia-Pacific. It is a trusted component across OEM machine builders, panel integrators, and MRO procurement teams worldwide.

Key Features & Benefits
- 110VAC Coil: Directly driven from standard North American and Asian industrial control voltage rails — no step-down transformer required.
- DPDT Contact Set: Two independent switching circuits in one compact body, ideal for interlocking, reversing, and signal routing applications.
- Octal 8-Pin Plug-In Design: Tool-free replacement in compatible relay sockets (e.g., Honeywell SZR-SY2 socket); minimizes panel downtime during maintenance.
- High Contact Rating (10A): Handles resistive, inductive, and motor loads without derating in most standard applications.
- Wide Temperature Range: Operates reliably from -40°C to +70°C, suitable for outdoor enclosures, cold-storage facilities, and high-ambient machine rooms.
- Long Mechanical Life: 10 million+ operations ensure multi-year service life in high-cycle automation environments.
- Transparent Cover Option: Visual coil energization status without opening the panel — reduces diagnostic time.
- Global Certifications: UL/CSA/CE marks support export machine compliance across major markets.
Industry & Equipment Applications
- PLC Output Expansion: Interface between low-current PLC digital outputs and high-current field devices (solenoids, contactors, indicators).
- Machine Tool Control: Spindle direction interlocking, axis limit switching, and safety relay circuits on CNC and conventional machines.
- HVAC & Building Automation: Fan coil unit switching, damper actuator control, and alarm annunciation panels.
- Conveyor & Material Handling: Motor starter auxiliary contacts, zone control, and jam-detection interlocks.
- Food & Beverage Processing: Wash-down adjacent control panels requiring reliable switching in humid environments.
- Water Treatment & Pumping Stations: Pump start/stop sequencing and level-switch signal conditioning.

Frequently Asked Questions
- Q: Is the SZR-LY2-N1 110VAC the same as the LY2N-J 110VAC?
- A: The SZR-LY2-N1 is Honeywell’s designation for a relay equivalent to the LY2 octal footprint. While the pin layout is compatible with standard LY2 sockets, always verify the exact part number with your datasheet before substitution in safety-critical circuits.
- Q: What socket is required for the SZR-LY2-N1?
- A: The Honeywell SZR-SY2 8-pin octal socket is the recommended mating socket. Standard PTF08A or equivalent 8-pin octal sockets from other manufacturers are also dimensionally compatible.
- Q: Can this relay switch DC loads?
- A: Yes. The contacts are rated for 10A @ 30VDC resistive. For inductive DC loads, apply appropriate derating and consider arc suppression (flyback diode or RC snubber) to extend contact life.
- Q: Do you provide a Certificate of Conformance?
- A: Yes. A CoC is available upon request for all orders. Please specify this requirement when submitting your RFQ.
- Q: What is the lead time for the SZR-LY2-N1 110VAC?
- A: Standard in-stock orders typically ship within 3–5 business days. For large volume orders, lead time will be confirmed at quotation stage. Contact us for urgent requirements.
- Q: Is this product RoHS compliant?
- A: Honeywell’s SZR Series relays are manufactured to comply with RoHS directives. Please request the current compliance declaration if required for your project documentation.
