Time Delay Relays all include a combination of a solid state timing circuit and an electromechanical relay output. This combination provides the user with isolation between the operating and load voltages and multiple switching contacts in either SPDT or DPDT forms. Most of the relay contacts are rated 10 amps resistive @ 240 VAC.

Time Delay Relays: Plug-in Package -- 8 or 11 Pin Base
These products are housed in the popular octal or 11 pin plug-in package and require an accessory socket for connection and mounting. A complete selection of time delay ranges and adjustment methods are available.
