I have a Control System Panel having a PLC system and Control Relays installed in the panel. This panel is to be subjected to the "Seismic Shake Table Test with 5OBE + 1 SSE vibration level". The "Electromechanical SLIM Relay, 24V DC operated, 6mm Thick SLIM Type" is a major component in this panel (250+ Nos quantity).
I understand that electromechanical relay has a reed switch that may move due to vibrations hence the Shake Table Test will fail if any of the relay becomes non operative after the vibrations.
Whether I need to go for alternate type of relays (Such as Solid state type relay SSR ? An SSR activates the Transistor base and the output (emitter of Transistor) will drive the field output load .
Will the electromechanical relay pass a Seismic vibrations of SSE level ?
Appreciate any expert opinion and suggestions on the above.
