Product Description

Touch-Plate CPS-8004B transformers are specifically intended for use in pre-wired CPS, RCP & MCP relay panels, which were installed between 1985 and 2008. This CPS-8004 is to be used in panels with more than 6 relays. Panels with less than 6 relays will want to use the CPS-8002 transformer.

This transformer is used with the 3000-PL relays, never with the 2500-B or 3000 relays. Homes with 3000 relays or the discontinued 2500-B relays need to use the TPS-0120 transformer.

Q & A

Can I replace my CPS-8002 transformer with this CPS-8004B?
Yes. The CPS-8004B is a larger transformer, but both this one and the CPS-8002 and the CPS-8004 have the same operating voltages. Please note that the mounting bracket is slightly different on this new transformer and may require some adjustment to install. Touch-Plate CPS-8002 transverters were used only in CPS, RCP & MCP relay panels, which were sold from the 80's-late 90's. The CPS-8002 was the smaller version of the CPS8004 transformer and was discontinued several years ago.
