RS485 / RS232 SPD
RS-485 and RS-232 serial links carry Modbus RTU, Profibus, BMS and energy-meter data across plants, solar parks and building services, and are a common lightning entry path into PLCs, inverters and data loggers. LPES supplies DIN-rail serial-line SPDs with gas discharge tube and TVS diode stages, low capacitance for baud rates up to 10 Mbps, tested to IEC 61643-21 Category C2, in 2-wire and 4-wire versions with screw terminals for SCADA, solar monitoring and building automation networks.
