Altronix PT2724 2-Channel 365-Day Programmable Timer Relay Board

Overview

The Altronix PT2724 is a dual-channel, 365-day programmable timer relay board designed for commercial security and building automation applications where you need time-based control of access, lighting, locking hardware, or auxiliary devices without relying on a VMS or controller to handle scheduling. If you're managing scheduled relay events across the week — door unlock schedules, lighting triggers, alarm arm/disarm automation — the PT2724 handles that logic independently at the board level, accepting 12 or 24VAC/VDC input so it drops into virtually any Altronix power distribution chassis or standalone panel already in the field.

Key Features

• Dual Independent Relay Channels: Two separately programmable relay outputs let you control two distinct circuits — for example, a door strike on channel one and a lighting circuit on channel two — without installing a second timer board or adding a separate controller. Each channel runs its own schedule, reducing wiring complexity and panel real estate.
• 350 Events Per Week: With up to 350 programmable weekly events, the PT2724 supports dense scheduling scenarios: multiple lock/unlock cycles per day, staggered shift access, after-hours automation, and weekend overrides — all without additional programming hardware. Most commercial installations never approach this ceiling, which means you have significant headroom for schedule changes without hitting board limits.
• 10 Programmable Holiday Dates: The on-board holiday calendar stores up to 10 user-defined dates that automatically override the standard weekly schedule. This is the spec that separates a basic weekly timer from a board suitable for year-round unattended operation — you set holiday lockouts once and the board handles them without manual intervention on the day.
• 10A / 120VAC or 28VDC Relay Contact Rating: The relay contacts are rated for 10A at 120VAC or 28VDC, which means the PT2724 can switch door strikes, magnetic locks, lighting contactors, and other inductive or resistive loads that would exceed the output capacity of lighter-duty timer modules. Verify your load's inrush current against the 10A rating before wiring high-inrush magnetic contactors directly.
• Dual Voltage Input — 12 or 24VAC/VDC: The board accepts 12 or 24 volts AC or DC, making it compatible with the overwhelming majority of Altronix power supplies and multi-output chassis already deployed in commercial security panels. No dedicated transformer or isolated supply needed in most installations — tap an available output on an existing access control power supply and you're wired.
• Low Standby Current Draw: At 10mA with relays off and 50mA with relays energized, the PT2724 imposes minimal load on the host supply. On a multi-board installation, this is the difference between staying within a supply's amp budget and needing an additional power source. Calculate total relay-on current if multiple channels are simultaneously energized in your schedule.
• Wide Operating Temperature Range: Rated -20°C to 49°C operating (-25°C to 70°C storage), the board handles unheated utility rooms, parking structure panels, and exterior enclosures in temperate climates without additional thermal management. This range covers most North American commercial installations year-round without a heated enclosure.
• Compact Board Footprint: At 5.25
