Device designed for binary detection of voltage presence on busbars and traction-network sections, with programmable thresholds from 50 V to 4200 V. 4800 V insulation and EN 50123-1 and EN 50155 certification enable direct use in high-speed disconnector control circuits and earthing-switch interlock systems. The output signal is transmitted to PLC controllers as a binary safety condition that must be satisfied before any switching operation in the high-voltage zone.
