Greetings. We inherited some flame relays made by Krom Schroeder (model IFW T-N). In a nutshell, these are small 120 volt devices used for the monitoring of gas burners. From the brochure:
Here is what the guts look like (keep in mind this was removed from an existing installation elswhere):
Acc. to the manual, the general principle is that as soon as the IFW 15T-N sees a flame, it switches two contacts: a normally closed contact, which is situated between terminals 6 and 7, and a normally open contact, which is situated between terminals 8 and 9. The green lamp indicates that the burner is on.
The manual gives several wiring options (ionization or UV control). We would be installing with ionization, which says this:
Given all of this, does it appear that we could pass the signal from this device into one of our EPICs or Rio’s, so then we can use this information to set off alarms or other logic functions? As far as I can tell, this device is simply looking for continuity of electricity.
Thanks in advance for anyone’s input.
