Description
The Seco-Larm SA-027HQ 365-Day Annual Timer with Two Relay Outputs is a robust, year‑long automation solution built for professionals who need reliable, holiday‑aware control of two independent circuits—perfect for exterior lighting, access control sequences, HVAC, and security systems.
- Two Form C relays: Each relay can be set to normally open or normally closed and supports 10A at 14VDC, with one egress input per relay for flexible control of two separate circuits.
- 198 programmable events: Plan up to 99 events per relay (198 total) across a full year, with each event selectable weekly, daily, or hourly for precise timing.
- Flexible event outputs: Configure events to disable, turn ON, turn OFF, shunt, or execute a momentary action (1–99 seconds) to match diverse automation needs.
- 20 programmable holidays: Create holiday schedules to skip or modify regular timer behavior, ensuring correct operation on special dates.
- Tandem mode: Run both relays simultaneously for synchronized actions, simplifying complex multi-point automation sequences.
- First-person-in function: Instantly interrupt normal timer operation for quick manual control when immediate intervention is required.
- Passcode protection: Enable or disable a passcode to secure programming and prevent unauthorized changes.
- Block programming: Define consecutive-day repetitions to speed up long schedules and reduce setup time.
- Power reliability and clock accuracy: Built‑in clock backup capacitor preserves date/time for 7–10 days after power loss; supports an external backup battery (not included) for enhanced resilience; leap year compensation keeps the calendar accurate.
- DST and time accuracy: Easily switch between Standard and Daylight Saving Time to maintain correct schedules year‑round.
- User-friendly programming: Alphanumeric backlit LCD display makes setup and editing straightforward, even in challenging lighting conditions.
- Easy installation: Exposed terminals simplify wiring and field adjustments during deployment and service.
- Mission-critical reliability: Purpose-built for precise year-long scheduling with holidays, robust backup options, and dual-relay control for multi-point automation.
This timer delivers dependable, holiday-aware automation for two circuits across an entire year. It’s ideal for installations where consistent timing matters—even through power interruptions and calendar changes—while giving you flexible control, secure programming, and practical features like override, tandem operation, and easy wiring. Whether you’re orchestrating exterior lighting, door access sequences, or coordinated HVAC events, the SA-027HQ provides concrete, two‑relay scheduling capabilities that adapt to real-world demands.
