Data Line Protection
In many office and industrial locations, data lines (such as RS-232) and AC power
lines run in close proximity to each other which often results in voltage spikes being
induced onto the data line, causing damage to sensitive equipment.
Protection Requirements
Data lines should be protected against over-voltages that can exceed 1500V and
surge currents up to 50A.
Data Line Reference Circuit
Figure 3-35 shows how a SIDACtor is used to protect low voltage data line circuits.
