Author Topic: Xetrol IV Dimmer Relays Joshua Waaland Jedi Master Film Handler Posts: 800 From: Cleveland, Ohio Registered: Dec 1999 posted 09-16-2004 02:49 PM                     I just bought a used Xetrol IV dimmer for my screening room. It is missing the relays from the circuit board. If I use a Eprad Co-Operator or any other automation are these relays still necessary? If so can someone tell me the info on these so I can buy some more. I faxed Xetron and they gave me a price of $48 each. I am sure I can get them through Newark Electronics for cheaper than this. Can somebody give me the part number off of one? Thanks. Josh  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

The Package style is KHAU ((Potter and Brumfield) Unless I miss my guess...they are KHAU17A11-12 Steve  |  IP: Logged Joshua Waaland Jedi Master Film Handler Posts: 800 From: Cleveland, Ohio Registered: Dec 1999 posted 09-16-2004 09:31 PM                     Steve, You are right about them being Potter and Brumfield. When I looked at the circuit board the socket read Potter and Brumfield. The schematic that I downloaded from the manual warehouse says that they are 4PDT 12 VAC for the serial number of the one I have. Unfortunately though I don't know enough about electronics or relays to know the differences between a switching relay or a power relay or half the other 100 different kinds listed in the Newark catalog. I appreciate the help. I will try to look that number up. Thanks Josh  |  IP: Logged
