Description
The OP-TIP1000 is a straightforward mechanical 24‑hour plug‑in timer intended for basic time control in UK homes and light commercial settings. It’s a captive‑tappet (segment) timer that plugs into a standard BS1363 wall socket and provides a switched BS1363 shuttered output socket for whatever appliance you need to control. Each tappet represents a 15‑minute block, so you can programme repeating on/off periods across a full day in quarter‑hour steps.
How it works and where it fits
Inside the case there’s a synchronous 24‑hour dial driven from the mains; the captive tappets around the dial move with the clock and operate a single switching contact. Set the tappets for the times you want the timer to be “on” and leave the others up for “off”. A three‑position manual override lets you force the output on, off or return to the timed programme. Because it’s mains‑synchronised the unit keeps good time without batteries (typical accuracy around ±2.5 seconds per day) and draws very little power (about 1 VA at 230 V).
Key specifications
- Supply: 220–240 V AC, 50 Hz
- Segment interval: 15 minutes (24‑hour captive tappet)
- Resistive rating: 13 A at 230/240 V
- Inductive rating: 2 A (cos φ 0.6)
- Dimensions: 130 × 68.5 × 42 mm; weight ≈ 150 g
- Power consumption: approx. 1 VA at 230 V
- Operating (temperature) range: approximately −10 °C to +55 °C
- Protection/class: Class II (double insulated), indoor use (IP20)
Practical use and suitability
This is a no‑frills solution for repeat daily schedules: think immersion heaters on a repeating daytime pattern, simple room or garden lighting, fan heaters (within rating) and other resistive loads that need the same daily programme every day. The captive‑tappet system is quick to set and easy for anyone to understand — you can see the full day at a glance.
Because the timer’s contact is rated only to 13 A resistive and a low inductive current it’s not suitable for direct switching of high inrush or specialised lamp types. The manufacturer’s documentation warns against using it to switch HID, SON or many LED lamp fittings directly; those loads can need a much larger inrush current or have electronic drivers that don’t work well with basic mechanical contacts. For pumps, motors or installations where startup currents or inductive loads exceed the unit’s ratings, use the timer to control a suitably rated contactor or relay instead.
Installation and everyday operation
Installation is simply plug and play: insert the timer into a normal UK three‑pin socket and plug the appliance into the timer’s shuttered socket. The front dial shows the 24‑hour cycle; press the tappets out for on or leave them in for off (or follow the engraved instructions on the casing). The three manual positions (Fix On / Timed / Fix Off) allow temporary bypass of the programmed schedule without changing the tappet positions — handy if you need to keep something on for a day or disable the timer temporarily.
The unit is compact and light so it won’t block adjacent sockets in many typical socket arrangements; the physical dimensions are 130 × 68.5 × 42 mm. It’s specified for indoor use only (IP20), so keep it dry and out of overly dusty environments. As a Class II device it’s double insulated and doesn’t rely on an earth connection for safety, but appliances you connect should still be used and earthed in accordance with their own requirements.
Advantages and realistic limitations
- Advantages: simple to set, mains‑synchronised accuracy, low standby power, clear 24‑hour view and manual override.
- Limitations: fixed 15‑minute minimum step (no fine sub‑15‑minute programming); modest contact ratings (13 A resistive / 2 A inductive), indoor‑only and mechanical contacts that will wear over years of heavy switching.
If your needs are a repeating daily schedule with quarter‑hour resolution and you’re switching straightforward resistive loads, the OP‑TIP1000 is a durable, low‑cost pick. If you need more granularity, weekly programming, or to switch motors, modern LED fittings or heavy loads directly, choose an electronic timer or use this unit to drive a properly rated contactor and protect the timer from excessive current and inrush.
