The intent and purpose of this document is to:
(1) Establish a standard reference for determining and definingparameters needed to specify ac Solid State Relays (SSR) and HybridSolid State Relays (HSSR) which employ a single isolated input andare designed for switching of ac lines with maximums of 500 Hz infrequency, 300 Vac in voltage and 50 amperes in current.
(2) Develop uniform methods and techniques for measuring theseparameters.
This standard does not encompass relays that are designed forsensing or performing special logic (e.g. timers, current orvoltage sensors, proximity switches, etc.), In the case of conflictbetween this general standard and any individual standard or detailrelay specification, the individual specification shall govern.
Several new classifications of relay types have been developedand standardized in recent years. These new types are distinguishedprimarily by the physical principles employed in their switchingfunctions which have been made possible by utilization of solidstate devices and technology. As a result, four major relay groups(see definitions) are now considered to have industry-widerecognition and are listed below – although this standard proposesto cover only two of the four groups.
