A standard optocoupler datasheet is divided into eight critical sections. Here is what you need to look for.
A 3.3V GPIO cannot drive a 24V industrial PLC input. Use an optocoupler: 1458 optocoupler datasheet
: Provides high isolation voltage, typically around 5300 Vrms , and high common-mode transient immunity (CMR) of 50 kV/µs . A standard optocoupler datasheet is divided into eight
This light-based transmission path ensures that there is no direct electrical connection between the input and output, protecting the control circuitry from electromagnetic interference (EMI) and power surges. LTC1458/LTC1458L - Analog Devices typically around 5300 Vrms
