OP-TS211.1 24 Hour Quartz Time Switch, Surface, Flush or DIN Rail

24 hour quartz time switch with 150 hour power reserve

The Optimum OP-TS211.1 is a single-channel quartz time switch running a daily programme on 15 minute tappet intervals. Its stand-out feature is a 150 hour running reserve — if the supply is interrupted, the programme and time are held for over six days, so you're not resetting the clock after every power cut.

Flexible mounting makes it suitable for consumer units, control panels and surface installations alike.

Frequently Asked Questions

Q: Where can I buy a DIN rail time switch in Ireland?

Q: How much does the OP-TS211.1 cost?
A: It costs €94.53 including VAT, with free delivery across Ireland.

Q: What does the 150 hour reserve actually do?
A: If the power goes off, the quartz movement keeps the time and programme running for over six days. You come back to a timer still on schedule instead of a flashing clock that needs resetting.

Q: Can it go in a consumer unit?
A: Yes. It mounts on 35 mm DIN rail, and also surface or flush, so the same unit suits a consumer unit, a control panel or a wall.

Q: Can I use it to switch LED lighting?
A: Up to 100 W of LED directly. Above that, or for any discharge lighting, the load must go through a suitably rated contactor.

Q: Do I need an electrician to install it?
A: Yes. It wires into a fixed circuit, so it should be installed by a registered electrician in accordance with I.S. 10101.

Q: Do you deliver across Ireland?
A: Yes. We deliver to every county in the Republic of Ireland, and you can also collect from our Rathcoole store.
