Stand alone real time clock

[khanz]

Hi all,
Is there any stand alone real time clock module available in the market, which has a minimum of 4 relay output. Thanks in advance.

I ran across a building controls controller today, a Honeywell XL50 or Excel 50(?) It had a date/time calendar, what I'd call a 'real time clock' with a number of I/O points, but I didn't read it real close, so I'm not sure if it had 4 relay outputs or not.

The HVAC or building controls market probably has packaged stuff like a what you describe.

any of those small 'plc':s, Siemens Logo etc. can do just that.

i second the vote for the smart relays (logo, pico, easy relay)

As mentioned - most programmable relays have this function. Also Omron make a unit called the H5S which is available as a weekly or yearly time clock (2 or 4 outputs). Another brand I have come across is THEBEN which is quite cost effective and they have heaps of different models.
