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.
