Answer Posted / Abhinav Kumar Srivastav
Relays are electromechanical devices and have contact bounce issues, response time delays, power consumption, and a limited lifespan compared to solid-state digital input modules like SCADA (Supervisory Control and Data Acquisition) systems or PLCs (Programmable Logic Controllers), which offer faster response times, higher reliability, and lower power consumption.
