SSRs vs EMRs - 10/10/2022

Solid State Relays (SSRs) vs Electromechanical Relays (EMRs) Solid state relays are switching devices made with electronic components. We use the word «relays» by analogy with electromechanical relays which have galvanic isolation of the control circuit and the switched circuit. “Solid state” refers to the fact that these devices do not have moving parts. A […]
