Altronix TEMPO724Q Network Programmable 24/7 Timer with Relay Output

Overview

The Altronix TEMPO724Q is a network-programmable weekly timer designed for commercial security and building automation applications where scheduled relay switching needs to be centrally managed, reliably executed, and immune to battery failure. Rather than relying on a local clock module that drifts or dies, the TEMPO724Q draws its time reference and configuration from the network — a meaningful operational advantage in multi-site deployments where keeping dozens of local timers synchronized is a maintenance liability. Integrators deploying door lock schedules, lighting control circuits, HVAC interlocks, or access control auxiliary outputs will find this board-level device fits cleanly into existing enclosures alongside Altronix power distribution hardware. It accepts 12VDC or 24VDC input and can also be powered directly via PoE (802.3af Class 3, 12.95W max), so you can drop it anywhere a network drop reaches without running a separate power feed.

Key Features

• 420 programmable events per week: That's up to 60 distinct on/off switching events per day, which is more than enough headroom for multi-shift facilities, staggered access schedules, or mixed-use buildings with different zone requirements. You won't hit the event ceiling in any realistic commercial deployment.
• 30 holiday date overrides: Program up to 30 calendar dates where the standard weekly schedule is suspended — useful for facilities that lock down on federal holidays, close for inventory, or run reduced-access weekends. No manual intervention required on the day itself.
• Dual-voltage DC input (12VDC / 24VDC) plus PoE: The TEMPO724Q works with either 12V or 24V DC systems, which covers the vast majority of Altronix and third-party power enclosures already in the field. The Class 3 PoE input (up to 12.95W) means you can power it from a standard 802.3af switch port — no dedicated PSU, no additional wiring run.
• 5A relay contact rating (24VDC / 120VAC): The output relay handles 5 amps at either 24VDC or 120VAC, which is sufficient for door strikes, mag-locks, lighting circuits, and most electrified hardware. Verify your load draw before wiring — 5A is the ceiling, not a continuous recommendation for inductive loads without a suppression diode.
• Auxiliary power output for peripheral devices: The board provides a regulated 12V at 100mA or 24V at 80mA auxiliary output, enough to power a small sensor, reader status LED, or tamper device co-located in the same enclosure. This eliminates the need for a separate tap off the main distribution bus for low-draw accessories.
• Low standby current draw: At 10mA with the relay off and 50mA with the relay energized, the TEMPO724Q adds negligible load to your power budget. On a 12V system, that's under 0.6W idle — relevant when you're calculating total draw across a multi-device enclosure with a monitored power supply.
• Wide operating temperature range (-20°C to 49°C): Covers most indoor and protected-outdoor enclosure environments in North American climates. It won't operate in unheated outdoor enclosures in extreme northern winters, but for conditioned equipment rooms, IDF closets, and interior security panels, the range is more than adequate.
• Compact board form factor (5.5
