Description
The Seco-Larm SA-025Q Multi-Purpose Programmable Timer is a compact timing relay designed for automatic control across security, access, and automation applications. It delivers flexible triggering and reliable timing in one easy-to-set package—perfect for installers, facilities managers, and automation enthusiasts who want precise control without complex wiring.
- Form-C relay output: 10A at 24VDC or 250VAC, enabling reliable control of diverse loads such as door strikes, alarms, lights, and pumps.
- Timing range: Adjustable from 1 second up to 60 minutes to cover both quick delays and longer sequencing needs.
- Trigger options: Activate via a normally open positive input, a normally closed negative input, or simply by powering up the unit for convenient integration.
- Relay activation modes: Start at the beginning of the timing cycle, end of the cycle, or engage for a one-second pulse at cycle end for signaling or reset actions.
- Pulse or steady output: Choose between a pulsing (flashing) indication or a steady-on state to suit signaling, gating, or load control applications.
- Power and sensing: Auto-sensing operation from 12–24VDC, simplifying installation across different system configurations.
- Current draw: Very low standby current (<1 mA) and about 40 mA when energized, helping minimize power use in continuous-use scenarios.
- Programming interface: DIP-switch control with no jumpers required, enabling quick setup and on-site adjustments without rewiring.
- Manual reset: Built-in reset function allows a fast restart of the timing cycle when needed.
- Compact, versatile design: A space-efficient timing relay crafted for real-world installations where space and straightforward wiring matter.
- Load versatility: Form-C contacts support a wide range of loads, making the SA-025Q a flexible replacement for multiple single-purpose timers.
The SA-025Q helps you sequence devices—doors, alarms, lights, pumps, or signaling circuits—precisely when you need them. It consolidates multiple timing scenarios into one adaptable timer, reducing the need for separate modules and simplifying maintenance. This makes it ideal for security installers, facilities managers, and automation hobbyists who require dependable timing without intricate wiring. Practical use cases include delaying a door strike after a sensor detects entry, pulsing a beacon at the end of a process, or holding a device ON for a defined period after power-up. Practical tips: map your trigger source to NO or NC inputs to match your existing logic, leverage the end-of-cycle one-second pulse for signaling or reset actions, and use DIP-switch programming to finalize timing and behavior quickly without tools. For best results, ensure your 12–24VDC supply remains stable and verify that the load is within the 10A/250VAC or 10A/24VDC rating of the Form-C contacts.
