24vac photocell

[wyreman]

I have a ems with an photocell analog input and the photocell has been erratic.
I am looking to simply replace photocell but find that a 120vac photocell will not switch the 24vac monitoring current.

Can anyone recommend a brand and also Who sells the 24vac pc?
ie http://bit.ly/1gfhcsn

I find some on amazon : torx, etc and the prices all are all over, from $5-$450
And I really need it now.

Funny that the switch wont move with lesser voltage.

thx

And it's just a temp work around, the whole antique EMS is being switched over next few weeks.
It's either replace the pc, leave 'em on, or ...

timer
120v pc to relay etc...
try and get another pc signal from a remote bacnet system

too much trouble for the temp fix...
oh well, thanks anyway
